If you bought a convertible, would the top spend most of its life bundled up behind the cockpit, or deployed over your head? Unless you’re an extremely hearty soul, I’m betting the top will most frequently be in roof mode for Autopians reading this site in the majority of the USA and Canada. In my neck of the woods, I would certainly be in top-up mode for most drives.
If you do brave the elements in your ragtop during snow removal season, a good option might be installing a rigid hardtop on your pride and joy for the time between Halloween and six weeks after the groundhog has seen his shadow. With a firm roof bolted in place, you’ll be able to enjoy the winter in cozy warmth without having to drive in a Snuggie or purchase a clapped-out Dodge Dynasty as a winter beater, selected purely for its ability to throw heat.


Recently, Thomas showed us a hardtop for a Porsche that not only kept the chills away but also dramatically changed the appearance of the car. Note that I didn’t say it necessarily improved the looks.

This concept got me thinking: how many other open-topped cars out there could I screw up or accidentally improve by doing the same?
Stopping The Drop
Convertibles in general are a dying breed; only 0.6 percent of new cars sold now have opening roofs, which is down from around 2 percent in the mid-2000s. The Ford Mustang is one of the last remaining convertibles, and 2023 sales were down a whopping 87 percent from 2001. Somehow having a car with a cloth body part (where a big knife could allow access to someone’s valuables) has less appeal these days where, in most areas, it’s either too hot or too cold to open up to the sky anyway. Today, with air conditioning standard on virtually every model, most people just use their car as just one more place to talk on the phone.
In the late 1990s we thought that convertible hardtops would be the way of the future: the best of both worlds. However, by the close of the 2000s many buyers found the ‘best of both worlds’ came at a heavy price both financially and in terms of cargo space, since all that glass and sheetmetal has to go somewhere when it’s down. The mechanisms can be notoriously costly and complex to put right if they fail mid-cycle in a rainstorm.


Of course, some luxury cars like old Mercedes SLs and Cadillac Allante offered simpler removeable factory hardtops for the cold months, though they required two strong workers or a hoist in the garage that you would assume someone with $90,000 to buy a car in 1989 would have access to.

Convertibles were once a status symbol, so much so that numerous companies even leaned into the idea of making silly fake ones during the malaise era when drop tops were going to be subject to a ban by the NHTSA rollover standards that never happened. At least the early canvas “carriage roofs” as stuck on this steel-roofed Bill Blass Lincoln Mark V were sort of convincing:

In some ways, having a steel or fiberglass hardtop on your convertible negates this visual “advantage”. For the most part, convertible hardtops (and, of course, the manually removed ones) don’t actually change the appearance of the car much at all; once installed, it now just looks like you bought some run-of-the-mill coupe.
What if the hardtop did actually make a drastic alteration to your car’s styling when it was installed? As Thomas mentioned, there’s at least one example of this out there.
Is That A Porch? Well, It Sort Of Has A Porch Now
Something didn’t look right. The picture of the Porsche Cayman that Thomas posted seemed sort of off, like it was one of those AI images where people have six fingers on each hand.

The reason? It turns out this wasn’t a Cayman at all, but instead an old Boxster with an aftermarket hardtop. This makes sense since there was never a Cayman version of the first series Boxster from the factory. Thomas’s research found this hardtop on ebay that also replaces the trunk lid to help with the visual ruse (and if you don’t mind being blind to the rear you also have space to stuff a few extra duffel bags behind the headrests):

As Thomas pointed out in the post, the end result looks good from afar but is far from good, with a cornucopia of panel gaps and the expected limitations of a non-factory creation.

Many people might cry out “just get a Cayman, dammit,” but if you’re debating whether or not to spend three grand on a giant lid for your first-gen Boxster then you probably don’t have the budget for a real Cayman anyway. Also, a real Cayman couldn’t take advantage of those rare, nice summer days here in the frozen tundra since the top is permanent.
No, I think the idea of a stretched-to-the-bumper hardtop is sound, but why not use the opportunity to give your car an altered appearance just for fun during an extremely not-fun time of year? Hell, we might even improve the functionality as well as the looks. Or one out of those two. Or neither. Aw, screw it, let’s get to work on a few examples!
Mustang King Cargo (not Mustang Ranch)
The Mustang has seen a variety of different body styles over the years, and for some reason Ford has sort of taken a step backwards in that area since the much-loved Fox platform. The ultra-popular generation of 1979-93 ‘Stang came in a convertible, a notchback coupe and an ultra-versatile hatchback configuration.

Fold down the rear seat and it’s amazing how much junk you could fit in the trunk. Look at all that space!

Today, the lineup of the last actual car that Ford builds has been reduced to a convertible and a fastback similar to the first generations of Mustang in the sixties, where all of your cargo needs to be jammed through a small trunk opening. This is progress? Even the unfairly-hated Mustang II gave you a liftback, for Chrissake.

You couldn’t easily install an actual tailgate to access luggage on a 2025 fastback Mustang above, but we don’t need to; we’re going increase cargo space and access with a custom hardtop on the available convertible model.
My inspiration is the ultra-hot Pontiac Firebird Trans Am Type K “shooting brake” concept with glass gullwing cargo doors which Mercedes Streeter reported on a little while back.

We can get the same kind of thing out of a Mustang convertible with a trick fiberglass hardtop. That’s right: lower the top, roll down the rear quarter windows, remove the trunk lid, possibly add a few small secondary brackets and in short order the King Cargo Hardtop can fit in place. You still have a back seat, the trunk space is accessible via gullwing glass windows, and you can pile more cargo up higher (an optional net would keep your suitcases from flying forward during braking and killing you Tom Mix style). I even added optional “T-tops” to give you some open air during those spring months before you’re ready to remove the top for summer.
Here’s an animation of the before and after installation:
Like it or loathe it, with a King Cargo Hardtop you’ll stay much warmer during the winter and be able to carry all of those extra presents to Grandma’s house during the holidays that you couldn’t in convertible format. Hell, if you’ve been waiting for a modern Volvo 1800ES you might never remove it.
Chrysler Sebtre or SebFire
Thanks to Michael Scott on The Office, the frequent use by rental agencies in period, or just because it’s a descendent of the K-car LeBaron, the Chrysler Sebring convertible doesn’t get a lot of respect. As one of the last mainstream non-sports-car convertible holdouts, it isn’t deserving of such scorn. The Sebring was not an e46 330i Cabriolet but it was never meant to be. An affordable convertible with real rear seats and no enthusiast pretensions. Is that a crime?
Oddly enough, at one point Chrysler even tried to appeal to different price points by offering both a fabric convertible and a retractable hardtop option at the same time.


Naturally, neither of these versions looks dramatically different from a standard coupe bodystyle, but we can change that. Lower the sort top, take off the back license plate, lose the trunk lid, and our multi-piece fastback hardtop gets installed.
Animation here so you don’t have to scroll up and down or do a “spot the changes” game:
Wait, you say, I see what happened! You just made something that looks like a legendary Chrysler Crossfire that had a few too many Five Guys burgers! Yes, that’s exactly what I did.

Enjoy the winter months with a fastback style that gives the appearance of a Rolls Royce Spectre that you bought off of Temu or Alibaba.
You can even still access cargo in the trunk via a small lid; note that I added new backup lights flanking the repositioned license plate (a body-colored filler panel covers the old recess).
Why would we do this? Why not? For better or worse, the CrossSebring recalls the underappreciated gems of the Dumber Chrysler era all in one vehicle. Best of all, it’s easily reversible and your ragtop (if so equipped) will get a few months less exposure.
Jeep Grenadiator
The appearance of some vehicles really stirs your emotions and gets the “cool car” juices flowing in your brain. It’s a good idea to sort of deconstruct the visual triggers making that happen and see if we can recreate it to get lightning in a bottle.
Let’s take two quick examples. One is the 21 windows VW Type 2 Transporter “Bus” from the sixties that is today one of the slowest vehicles without a real heater one can spend six figures on. The other example is the early Land Rover Defender (and, of course, by association, the Ineos Grenadier have-they-no-shame ripoff).


What is the most salient feature that makes people respond so positively to these, and what makes them so unique and special? For me it has to be the tall roof with the extra windows up high. This trick makes these things just look so spacious inside, and that glass allows for extra light and great views on your adventures.
A Jeep Wrangler is one of those machines that can be outfitted with more different factory and aftermarket hats than you can find in a Starter store. There are multi-piece hardtops with removable panels, half-doors and even some odd-looking fastback options. I might be missing it, but I haven’t seen one yet that could easily provide that same high-roof skylit appearance of the European favorites above to really transform the Jeep into something special when you can’t have the top removed. I can fix that.
The “Grenadiator” hardtop concept here gives you a raised area over the back seat and cargo area, with a sunroof above the driver and front seat. Skylights and a taller rear window provide extra light and headroom for people and cargo, so much so that you almost wonder if there’s room in the cargo area for more seats since sitting more upright is now an option.
You’ll want the animation to see the subtle change:
Another possible design could play off of the two-door Land Rover Defender or even the faux off-road Matra Rancho:

I’ll still use the four-door Wrangler but we’ll mimic the large rear side windows and use black graphics to visually fool your eye:
You thought you really wanted an old Defender, but I’m willing to bet that for many it’s just that cool window roof you were after. Sure, we’re stealing designs, but the Wrangler is so prevalent now that it’s nice to do some customization to make you stand out, especially if that customization improves the functionality and passenger experience, right? Plus, now your Jeep no longer looks like the one a middle-aged mom down the street drives with ducks on the dash; there’s an air of sophistication now so people will think you’re a skilled, cultured explorer or diplomat in a Zaire. Or not.
It’s Two Cars In One!
With today’s on-board electronics, myriad safety devices and regulations, customizing even a twenty-year-old car is not nearly as easy as might have been for people our parents’ age. Hard to imagine, but aftermarket hardtops on convertibles might be the last window of opportunity for a budding George Barris in the modern world.
I’ve shown just a few examples of the damage you can do; what are some other convertible candidates you can think of for a design-changing makeover (good OR bad) with a custom hardtop?
A Ford Maverick Could Be The Affordable, Practical Convertible The Market Is Missing – The Autopian
This ‘Cayman’ Is Actually A Boxster Wearing A Hat You Can Get From AliExpress – The Autopian
Hate The Pointed Pyramid Roof On The Tesla CyberTruck? Let’s Chop It Off – The Autopian
Absolutely nailed it with the Mustang here. And, yes, I was semi-seriously looking for an 1800ES a couple years back.
I still have a thing for the Volvo C30 and a part of me could see myself getting one and keeping it forever. The rear end is my favorite part.
We were just talking on the site about the Polestar version of the C30 that they only made a few hundred.
I still kind of want a C30 T5 too
Vague recollection, but I think there was an aftermarket hardtop for 1st-gen Mustang convertibles that turned it into a fastback. They could have easily sold a wagon version.
https://themustangsource.com/forums/f737/vert-fastback-conversion-i-figured-would-happen-508181/
Whoa! That’s really cool. There you go! See? It’s possible.
Aside from my usual appreciation of Bishop imagination, I have to point out for Autopian’s sake that that Firebird shooting brake concept actually appeared in an episode of the Rockford Files, driven by a con woman. Jim even nonchalantly acts like it’s a normal car.
I’ve seen a picture of him with the shooting brake and one of his Formula-dressed-up-as-an-Esprit Firebirds from the show.
Be still my heart….
I’d like to see a shooting break lid for the original Audi TT.
That Sebring is bringing heavy Honda Crosstour vibes and I dig the Jeep renderings! The Sebring convertible is actually the reason my wife and I now have a convertible. We had one as a rental, and it was enough to convince her that we needed to live a part-time, topless lifestyle (but not with a Sebring/200). So, in a way, I have a soft spot for that car.
Crosstour is what I saw as well
or just do what fiat did, leave the side frames and push back the canvas.
SmittyBilt already makes, or made, a Jeep hardtop like that. It was for the JK Wrangler generation, but it’s since been discontinued though.
IDK why they don’t make more Targa tops. Are they viewed as not cool as convertibles by convertible buyers? It’s the best of a convertible AND a hard top. I want a miata RF in the worst way.
I agree, but my guess is difficulty in engineering places to stash them (a manual targa should probably be 2-pieces to make them easier to manage and store) that also don’t allow them to become missiles, which points to making them power roofs, which a soft top is cheaper to do. They don’t even have manual sunroofs anymore (that I know of), though at least the Bronco comes with removable roof panels. Don’t know how they handle storage, but there’s certainly more space than a sports car has.
The constraints exist, yes, but I don’t buy they are an inhibitor if Mazda can do it in a vehicle the size of an MGB. Inhibitor of profit I suppose.
OK, I meant manual roof panels, but yeah, Mazda could do it because they already had the soft top and the RF top is power. They didn’t have much choice there as it would be expensive to change the BiW, so they came up with a design that reused the soft top stowage area and added a solid sail panel. I imagine operating all that mechanism would be difficult to do manually. Without the linkage, a solid single piece is awkward at best (a friend had a Del Sol and it was awkward to put back on alone without standing on the seats or worrying about scratching something and that had a fairly large trunk lid to stow it under that was easier to deal with than it would to stuff it vertically behind the seats like the Miata). To do this with an already low-volume coupe, I just doubt they could make a business case unless they’re expensive.
You’re probably right. I’m just tired of complicated things. 🙂
I really like that Mustang wagon. Makes me want to turn my Volt into a wagon.
Voltwagon?
If you bought a convertible, would the top spend most of its life bundled up behind the cockpit, or deployed over your head?
When I lived in Southern California I was surprised (and a little perturbed) with how on absolutely perfect top-down days nearly all the convertible tops were up. People, what’s the point of a convertible?
That is my biggest automotive pet peeve. Why did you buy a convertible if you aren’t going to put the top down on a beautiful 75 degree day?!? I live in San Jose and I see this all the time.
When I lived in LA – I had to find excuses to raise the roof.
My coworkers asked if my car even had a roof.
I think, similar to the spec sheet performance braggery of our times, it’s to be able to tell people you own a convertible. Sigh.
It’s probably like the people who buy the deluxe version of a car but never use the fancy radio and NAV. I have relatives like this. Aww cool car! Yeah but don’t touch any of those buttons b/c they don’t know what they do and they would really not like it if something changed that they could not change back. They have 18 speakers and listen to AM radio. I’ve seen people do this with electronics too. Bought the best one but takes zero advantage of its features.
I can swear and attest to the dearth of actual useable space in a Fox Body Mustang. Through a series of misfortunate circumstance I had to be the fifth body (I was 18 and skinny at the time) in a 4-person repo (mostly cars but also a tractor . . . don’t ask) crew one day. Somehow they chose an ’83 Mustang to drive around town in and I was stuffed under the hatch on a July Texas day. A Fairmont shooting brake would have been much preferable.
(edit) Or, This! https://imgur.com/tbgklkM
For four American-sized guys it certainly wouldn’t be great choice, but for a bunch of cargo in a sport coupe I think it will beat an F-body Camaro or Firebird.
Now we need an article on how much and what kind of cargo can a Mustang vs a Camaro fastback can actually carry. !!!
I did several major bachelor moves in the Navy while owning an ’81 Mustang hatch. Carried everything I owned long distances. Admittedly I didn’t have any furniture but I had tools, outdoors stuff, clothes, uniforms, bike, etc.
I know your pain: I was often the 3rd wheel to a couple with a 79 280zx
I spent 90 minutes in the back of a Karmann Ghia. Wasn’t that bad as the gas fumes made me lose track of consciousness after 3 miles.
I own a hard top convertible. They are exactly as advertised.
Much better noise blocking and blending in with the top up. Better for cold temps, too, and I don’t need to worry about someone taking a sheet rock knife to the top anytime I leave a quarter in the cup holder. Looks better (IMO) too.
But also, every time I raise or lower the top, I sweat bullets something will fail. If it ever does, I know I’m in for a world of wallet pain (BMW 4-seies). Even when it works, it makes even simple fixes painful.
Last year the plastic window guide for one of the rear windows broke. No problem, easy fix, cheap part. But of course, the roof must be down to remove the interior trim to get at it, and the roof refuses to move if it can’t lower the window. So 3 months and a specialty tool shipped from Germany later, and it finally gets done.
I still love it, bit I also fear it.
Fearful love: isn’t that the only kind of love to have for your car as an enthusiast? The kind of love that you will endure pain for.
So I have an BMW 330ci e46 convertible, with the additional hardtop. I’ve also owned a e36 convertible (no hard top.)
So the actual hardtop is pretty light, if you didn’t have to maneuver it just so to get the back pins in I think one person could do it, but there would be too much of a chance of scratching the paint. It’s easy for 2 people to lift and install it, and it even has 4 screw holes that are hidden under covers, so a garage hoist would be easy to do (unfortunately my garage/shop has a 14′ high roof, so that makes it a bit more difficult.)
I actually like the profile of the hardtop more than that of the coupe, but I’m also the crazy guy that likes the lines of my 69 Mustang Coupe over the fastback. (Side note, why does everyone ask if my Mustang is a fastback while they are looking at it, I mean, you’re looking at it, clearly it isn’t a fastback.)
Lastly, the insulation on the soft top of my e46 is much better than that on the e36, it isn’t nearly as loud with the top up, and much better insulated against heat and cold.
Lastly, I normally run with the top down. I have other cars to drive in the cold or bad weather. My hardtop usually just sits on top of the Mustang year round, partly due to the sagging headliner. My main daily driver was totaled in an accident last last year, and the next most fuel efficient car is the 330ci, so I bit the bullet, fixed the headliner in the hardtop with M Hurricane pattern fabric, and drove it for a month in the winter with the hardtop on until I got my replacement car.
Hear me out: a completely transparent bubble top for a Miata RF. I’m talking a full-on Jetsons-style plexiglas bubble. Will it make the cabin hot on sunny days? Yes. Will it be noisy? Probably also yes. Will it look cool as sin? You bet.
A tinted bubble. Shooting glasses yellow, acid green… whatever.
Yes! White Miatas with iMac color tints
Electrochromic glass. It was used a time or two, but seemed to die before taking off. Don’t know if it was an expense or reliability issue or if people just weren’t interested.
Around town here is or was a bubble topped 50’s Corvette. The story was that the original owner was tall and had a bubble top built to allow space for the tallness. That was cool enough, but the Corvette was copper colored and had a matching style and color trailer as well. Rumor was that someone was working with the owner to use the top to make a mold to be able to make others. Dont’ know what happened after that.
reminds me of the Nissan Pulsar NX with the exchangeable Rear hatches.
https://www.carscoops.com/2023/11/nissans-modular-pulsar-sportbak-was-a-coupe-wagon-and-pickup-in-one/
I was going to say, all that and no reference to the Pulsar NX!
Why didn’t you do a foxbody with a wagon top? The full sized hatch opening would be PERFECT for an addition.
You mean a Fairmont wagon?
I didn’t know that was a thing, and I love it.
Fastest car I’ve ever seen in action on the street was a Fairmont Futura that launched from a stoplight when I was in Gainesville, FL to pick up my 69 Mustang from a relatives house.
That Jeep top is awesome!!!
The Sebring is quite a choice there.
That Mustang King Cargo reminds me a lot of the 2004 Chevy Nomad concept. Good times.
Where have all the good concepts gone? And where are all the rods?
Holy shit a wagon top for the Mondial would be amazing and I want to see it. Too bad it doesn’t really work with mid-engined cars…right? Exhaust something something?
Also I think you mean “hardy.”
It’s like the enos / Miata people going what hardtop is that. Makes sense that has come to porshe now. That mustang looks like it could be euro market shooting brake quite the clown shoe.
With the first couple, it’s clear you were screwing around.
With the Jeep changes, it looks like you’re doing an actual product pitch. I’m sure those would sell well enough to pay for the fiberglass mold needed to make them.
WRONG- I am ALWAYS just screwing around.
My point is not that you’re not whimsical enough.
It’s just that I really think you’re onto something with the Jeep designs. If I had a Gladiator, I’d want one of these to give a little extra headroom for the rare times adults sit in the back, and to make it more unique.
Jeeps really are the top dog in bolt-on customizations. That’s a huge part of why they’ve remained so popular. It’s so cheap and easy to make them a bit different than factory stock, and equally cheap and easy to swap them back again if you haven’t resold your original parts.
Just kidding- I’m glad you like the Jeep concept! I have to believe that there’s something like that out there already.
There is! Several companies have made them over the years. You’re gonna have to get real weird before you find something that hasn’t been available on the Jeep aftermarket.
I searched “Wrangler Unlimited Safari Hard Top” and found some.
I’ll spoil the surprise and tell you that the Bishop’s look much nicer.
The front ‘roll bar’ and black accents send it over the top!
My first thought seeing the top image of the Mustang was the Nissan Pulsar NX.
I….don’t hate it, although I’ll stick with the fastback.
I actually ordered a Mustang convertible for a customer a couple months ago. It’ll be the first I’ve sold since..um (/checks notes)…2022.
You missed the best platform for this treatment. The Nissan Murano convertible, personally I think the Chrysler / Rolls treatment on a Murano could be cool.
The jeep africa concept was good enough https://moparinsiders.com/looking-back-at-the-jeep-wrangler-africa-concept/ a raised roof would be even better. Hell just a hard top that went the entire length of a gladiator to sleep in the back or have heat and air for the dogs, would get me to buy one. https://moparinsiders.com/looking-back-at-the-jeep-wrangler-africa-concept/
“Like it or loathe it, with a King Cargo Hardtop you’ll stay much warmer during the winter…”
The Mustang Convertible has a 3 layer top – which includes a 1cm thick insulating layer between the inner and outer layers.
It’s better insulated than the hardtop – and much better insulated than anything with a glass roof.
