Is It Live Or Is It Memorex?: 1999 Mercedes S320 vs 1998 Lexus LS400

Good morning! Today we’re looking at a couple of luxury cars, one of which “benchmarked” the other, which is a nice way of saying “unabashedly copied.” Is the copy even better than the real thing? We’ll find out.

Yesterday, we looked at a boring but clean car and a rough but interesting one, and it looks like condition won out over potential fun. I expected this one to go the other way, frankly, considering this group’s general dislike for J-cars, and the fact that it was up against a car that’s a stickshift and turbocharged and rear-wheel-drive. But sometimes I get surprised, and this was one of those times.

I’d take the Cavalier, to the surprise of probably no one, for two reasons: One, I hate rust, and two, I would enjoy it more on my local roads. We don’t have much for fun twisty roads around here, but we do have lots of flat, straight two-lane blacktop going between little towns, which sounds perfect in a small, leisurely convertible.

Now then: You only have to take a quick look at the luxury car market in the late ’80s to know where Toyota had its sights set with the Lexus LS400. The Mercedes-Benz S-Class was it, the top of the line, the fanciest, nicest, and at the time, best-built luxury sedan you could get. Did Toyota rise to meet the challenge? Oh yes. And then some.

But it has been decades since then, and both the LS400 and the S-Class have reached the bottom of their depreciation curves, letting the rest of us enjoy their fine qualities on a budget. Which one is the better beater? Let’s take a look and find out. Apologies if either or both of these cars are sold by the time you read this; I have a feeling they’ll sell quickly.

1999 Mercedes-Benz S320 – $2,500

00k0k 6xbdipvkxbt 0ci0t2 1200x900

Engine/drivetrain: 3.2-liter dual overhead cam inline 6, five-speed automatic, RWD

Location: Marina Del Rey, CA

Odometer reading: 191,000 miles

Operational status: Runs and drives great

The Mercedes-Benz W140 chassis S-Class had some gigantic shoes to fill. Its predecessor, the W126, was the car of choice for Wall Street tycoons, rappers, and tin-pot dictators around the world, and was well-known for being not only smooth and luxurious but also phenomenally well-built and reliable. The W140 upped the ante on technological features, and in doing so, lost a bit of the reliability, and ushered in the modern era of extremely complicated German cars. This is either the last “good” Mercedes or the first “bad” one, depending on who you ask.

The W140 was available with a wide range of engines, all the way up to a 6.0 liter V12. But this one makes do with a 3.2-liter twincam six, backed by a 5G-Tronic automatic transmission. One does not deign to shift one’s own gears in an S-Class. It may not be the fire-breather that the V8 and V12 cars are, but it will do nicely, thank you, and uses a lot less fuel. Like many Mercedes drivetrains, with proper maintenance it is capable of racking up some serious miles, and this one is approaching 200,000 and still runs just fine.

This S-Class wears Massachusetts plates, but the seller says it was “mostly a Florida car,” and now resides in California. Like Hank Snow, it’s been everywhere, man. The seller is now moving overseas and is therefore unloading it cheap.

It looks pretty good, but not great, as you might expect from a cheap twenty-five-year-old luxury car. There’s a bruise on the rear bumper, and it looks like there might be a little water intrusion into the taillights that should probably be addressed. Once again, we don’t get a photo of the driver’s seat, which probably means it’s damaged. People think they’re being so clever not showing it, but it’s literally the first thing you’re going to notice when you open the door. Just let us see it, so we can act accordingly.

1998 Lexus LS400 – $3,000

00u0u H0jjtqe5wpg 0if0dg 1200x900

Engine/drivetrain: 4.0-liter dual overhead cam V8, five-speed automatic, RWD

Location: San Gabriel, CA

Odometer reading: 89,000 miles

Operational status: Runs and drives great

If you’re old enough to remember when Lexus began, you probably remember this commercial, in which Lexus showed that it came to play. For one thing, 145 miles per hour? In a car built by Toyota? Such a thing was unthinkable to the average Camry owner. But beyond that, it was smooth enough to not disturb a stack of wine glasses on the hood, with the engine howling along at that speed? Now that was impressive.

00l0l 9kygbcbgmcy 0if0dg 1200x900

Unlike Mercedes, Lexus offered only a single engine in the LS, a four-liter V8, available only with an automatic transmission. This second-generation LS400 gained a fifth gear, bringing it even once again with Mercedes. These engines and transmissions are known for their incredible longevity, and for retaining that smoothness even with hundreds of thousands of miles on them. This one, at 89,000 miles, is just getting broken in.

Of course, it’s quiet and comfortable inside and loaded with all kinds of cool gadgets. This one shows some splits in the leather of both front seats, probably due to that warm California sun, and it also looks like the driver’s side headrest has been removed. It’s also missing a speaker grille on one rear door panel. I would say you could pop into a junkyard and find one, but I imagine LS400s are few and far between in junkyards.

00d0d 7zoxwzdehnc 0if0dg 1200x900

It looks pretty good outside, except for the plastic wheel centers, which always turn yellow and look like hell on these cars. I don’t know if it would be better to repaint them to match the wheels again, or just take them off, but they look awful and make the car look older and more run-down than it is. That not-really-a-color paint makes it look old and tired to me too, but maybe that’s just because I had a Corolla the exact same color that really was old and tired.

ADVERTISEMENT

Both of these cars strike me as pretty good deals, and that’s not often something you can say about cheap used luxury cars. But they both represent automakers at the top of their game, making the very best four-door sedans they could possibly make, and building them to last. I’d be happy to park either one in my garage, but I want to know what you all think. Do you want the real-deal German sedan, or the highly-polished Japanese interpretation?

I knee-jerk voted for the Mercedes since i have its bigger V8 brother in my driveway at the moment. But then i remembered it hasn’t run since…. October of 2023? wow yeah it’s been sitting for 12 months it might be time to pull some parts and junk the car

a sub 100k Lexus LS is probably the best money one could ever spend on a land yach

I don’t care so much about what the driver’s seat looks like on the Mercedes, but any car that has spent time in Florida must be presented with pictures of what’s under the floor mats. Probably some other crevices too.

I was going to go with the Merc, but then I scrolled dow to the mileage on the Lexus… Yeah, a sub 100k LS is really hard to argue with.

The W140 S 320 was fundamentally rock-solid, but I think the I6/SWB version of a W140 is quite missing the point, at least from an American perspective. Give me the LS 400.

And that isn’t a second-gen LS; it’s a first-gen.

No contest. The Merc was a nicer car when new but that’s just too many miles to trust for that car. That Lexus has many, many good miles ahead of it, and the flaws would be well worth fixing. LS400 all the way.

The S Class is nice, but not quite nice enough to beat out the low mileage & price on the Lexus.

I was going to deviate from my Mercedes obsession to go for the Lexus – but not THIS Lexus – because SO many red flags.
I’ll take the W140.

Lexus is the easy choice. Just fix that damaged driver seat and it looks like it’ll be perfect. Though that’s not a 1998 LS400. It looks like a 1994 or earlier one.
There is a chance that Lexus ad is a scam.

Assuming the Lexus ad is not a scam in some way, it gets my vote.

The Merc is a bit more attractive and the vintage means a bunch more reliable engine, But not so much at that particular mileage. Lexus for me even if it had the same high miles.

LS for the win. Toyota overbuilt that car to such a degree that I’m not surprised of its longevity. The low miles for the year I’d a nice bonus.

The Merc is nice but not the bulletproof version before it. Mercedes has been trading longevity for technology for quite a while now and this is the first salvo.

WOAH – hold on. Is this LS400 a 1998 or a c.1994? Because the article says 1998, but the pics look like a ‘94, and I foolishly can’t find the link.

I love me an old Lexus as much as the next guy, but the wrong year in the ad makes me wary

It’s not a ’98. If you can’t trust the seller to get that right, you can’t trust anything else they’re saying either.

LS all day long.
That Mercedes I-6 is solid and smooth, but it’s no match for a V8 cruiser like the Lexus. Half the mileage sealed the deal.
Now let’s start browsing for a headrest and front seat bottom covers

The Lexus wins by default. Even when new, the LS400 came in first place and the W140 came in last. https://www.caranddriver.com/reviews/comparison-test/a45860412/1998-audi-bmw-jaguar-lexus-mercedes-benz-luxury-sedans-archive-comparison-test/

Used, definitely Lexus. Well, duh, It’s a 90s Toyota.

Look, I like the W140 more than I should, but it’s just not a good car.

they’re both good cars and that I-6 was one of the most robust engines Mercedes has made over the last 3 decades.
But it’s no match for a smooth, million mile capable V8. The 6 cyl in a V8 comparo is the main reason the W140 got 5th place, there’s nothing wrong with the rest of the car, it was just too expensive for what it was.

I’d normally be on Team Benz but the patina of sticky, yellowing palm cheese on that steering wheel gives me the ick.

I chose the Merc. Not sure why, I guess I hate myself, but the Lexus has never felt as special as the Merc.

…it was smooth enough to not disturb a stack of wine glasses on the hood…

I preferred the ball bearing commercial, lovingly spoofed by SNL in the commercial for the Chameleon XLE.

LS400. No question about it. That engine has hit one million miles with complete maintenance…and so is very durable.
Second option would be a B Body Caprice….cheaper of course but a good DIY car and also very reliable if well maintained….

If this was a W220 vs a LS430, I’d be interested. But these are both too old to be fixable, especially the vacuum BS in the Merc and the myriad of tin-whisker infected computer modules in the LS. The vacuum problems on the Merc will drive you crazy, and the quest to find 35 year-old computer modules that still work will just plain kill you.
W123 Vs Cressida? Sign me up. W220 Vs LS430? Yes, absolutely. But these two both fall into the uncanny valley of unrepairableness.

The LS430 should be MORE durable than the W220……I do NOT get what you are saying. I am no Toyota/Lexus loyalist, but the LS430 was one of their best cars….

Even the Cadillac DTS after 06 and up should beat the W220 as well in the reliability department…aside from the hard-to-work on Northstar engine and lower build quality

I’m saying I’d rather have an older Merc S or a newer Merc S. This one is right in the problem/age sour spot.
Same with the LS. The 400s suffer from mind-blowing electrical failures. The truth is, a Lexus LS is made of thicker metal and better parts than a Carolla, but the computer chips are pretty much the same, except that the LS has a lot more of them.
And yeah, I’d take a DeVille or DTS IF it was made after 2009, when they “mostly” solved the head bolt issues.

Ramaswamy Narayanaswamy

But this issue with the LS400 I have NEVER heard of…
Most people online have never had these electrical problems..and it was supposedly VERY high in build quality….What you said is actually news to me, as usually Mercedes I expect electronic issues with…

Now, I am NOT justifying it as a purchase to be made above every car, but I believe in terms of value for money, this LS400 looks pretty good. Just my opinion…

The build quality on the chips in an LS400 isn’t any better than on other cars. But because there are so many of them, the failure of just a few can basically cripple the car, or make it hard to use.
So as this computer-chip dense car ages past 30 years, silicon crystallization within the circuit boards leads to shorts that essentially brick the chip module. Maybe the windows don’t roll down, maybe the transmission won’t shift, maybe the engine won’t start. It depends on which particular chips went bad.
Of course, Toyota didn’t build out a stock of spares to replace the chip modules on every LS 400 ever built. But because the rest of the car is built so well, it last forever- much longer than the electronics. So good luck finding a working ECU for a 1991 Lexus LS 400, it’s a unicorn.

You do have some valid points which ANY Toyota/Lexus Loyalist will FAIL to take into account…

The same issue DOES apply for German cars as well. The entire point of the LS400 was basically a competitor to the Germans….and being fully built in Japan also means that yes, parts availability may be an issue…Then again, wouldn’t old Lexus LX and GX cars also have computers and electronic modules that COULD be expensive to fix?

Michael Beranek

Yes, but at least the Germans built a lot of spares. Not as many as in the US, where they build more spares than anyone will every need.
But the Japanese have always been pretty stingy with spares. Combine that with a car who’s engine, transmission, body, etc. are superbly built to last forever, and the electronics become the weak link in the chain.
I believe there is a cottage industry of folks who will crack open your bricked module and REPAIR it, if possible. But they ain’t cheap.

Electronics. I know for a fact that the top of the car had some electronic issues and parts are hard to get for that…but I assume that towards the end of the production run, this was sorted…

Going against the grain and taking the Merc. I love the look of those and they are solid if it’s got the maintenance records. I can probably low-ball him down to throwaway car money too.
