Good morning! For our final single-make pairing of the week, we’re looking at two classic six-cylinder BMW sedans. They’re both north of 300,000 miles, but they’re both ready to drive off, according to the sellers.
Yesterday was all about Chevy, and I admit I kind of stacked the deck in favor of that Cavalier. I wanted to see it win, and win it did, by a landslide. That crossover whatever-it-is might as well be a toaster oven or a washing machine. I’m sure it’s fine, but honestly, it was hard to even find things to say about it. If I’m still here doing this in twenty years, we’ll check in on another Captiva (is that what it was called? I forget) and see if it’s aged any better by then.


A lot of you complained about the lack of an overdrive in the Cavalier’s transmission, but honestly, I don’t remember the TH125C being that bad on the highway. It has a lockup torque converter, which helps a lot, and you can cruise along at 70-75 all day with it. It’s just not as serene as it would be with a fourth gear.
Used BMWs have a terrible reputation here in the US. They’re complicated, high-maintenance, leak-prone, and misunderstood by American mechanics – and yet, here we have two very high-mileage examples that basically run and drive fine. Are they the outliers? Or is it just that they’re older models from before BMW started using six parts where one would do? Let’s take a look and find out.
1989 BMW 735i – $1,700

Engine/drivetrain: 3.5-liter overhead cam inline 6, four-speed automatic, RWD
Location: Portland, OR
Odometer reading: 300,000 miles
Operational status: Runs and drives well
The BMW 7 Series is the “boss’s car.” No junior executives or associates roll up to the office in a 7er. This car makes a statement; it tells everyone that you’ve arrived. Or at least, a new one does; a used 7 Series is ironically sometimes cheaper than the smaller ones. When my dad lived in Germany, he drove a 1990 730i, because it was so much cheaper than any 5 Series he could find for sale. I drove it when I visited him; it was a wonderful car to drive. By the time they get this cheap, they’re not going to impress anyone, but they’re still damn nice cars.

Lots of engines were available in the 7 Series over the years, but the simplest ways are sometimes the best ways, and I think that’s the case here. The 735 is powered by BMW’s tried-and-true M30 inline six, displacing 3.5 liters. It was available with a manual transmission behind it, but I think I’ve seen maybe two over the years so equipped. This one has the far more common four-speed automatic. It has crossed the 300,000-mile mark, and it still runs and drives well, according to the seller.

It’s a bit of a Ship of Theseus; the previous owner swapped out most of the tan interior with black. I think I would have liked the tan better. It’s in OK shape, but not great. For the price, you can’t complain too much, I suppose.

The outside is a bit piecemeal as well; two doors and one fender are from a different car, and they’re dark blue instead of black. I would imagine that means it was in a minor wreck, but it wasn’t enough to cause any title problems, fortunately. You could repaint it all to match, I suppose.
1998 BMW 528i – $1,900

Engine/drivetrain: 2.8-liter dual overhead cam inline 6, five-speed automatic, RWD
Location: Fremont, CA
Odometer reading: 329,000 miles
Operational status: Runs and drives well except for a hard 1-2 shift
Jumping forward a generation and down a model, we find this E39-chassis 528i. This is either the last “good” one or the first “bad” one, depending on how you feel about some of its technological advances. It’s certainly a more complicated car than the earlier models, but nowhere near as byzantine as current BMWs.

This one is an inline six as well, but it’s the more complex twin-cam M52, with BMW’s VANOS variable valve timing system. It also marks the start of BMW’s cooling system woes, with the plastic water pump impellers and self-destructing overflow tanks. This one has reached an impressive 329,000 miles, which means someone has taken care of the typical problems. It’s backed by a five-speed automatic, made by GM, usually a pretty reliable transmission. This one has a bit of an issue: it shifts hard into second gear, but otherwise drives fine. That could be low or dirty fluid, or it could be something more serious like a bad shift solenoid. You’d have to dig into it to find out.

It looks really good inside for the mileage. Someone took care of it. Normally I’d say that points to a one-owner car, but the ad doesn’t read that way. I get the impression the seller hasn’t had it very long. In any event, it looks like one of those cars that was rarely driven with more than one person in the car; there’s wear on the driver’s seat, but nowhere near as much on the other seats.

It’s hard to tell the exact condition of the exterior, because the photos are terrible and the car is dirty. But I don’t see anything obvious, just a couple of minor dents and some clear-coat failure on the rear bumper. I bet it cleans up nicely, though; I always liked this dark green that BMW used back then.
So there they are: two BMW sedans with well over 600,000 miles between them. One runs well but isn’t the greatest cosmetically, and the other looks better but might need a little mechanical work. They both feel like decent deals, though. Which one are you more willing to gamble on?
“A lot of you complained about the lack of an overdrive in the Cavalier’s transmission, but honestly, I don’t remember the TH125C being that bad on the highway.

‘Tis true. My Sunbird has the TH125C as well and I drove it 8+ hours from northwestern Kentucky to Detroit, Michigan last September for RADwood (and will do so again this year provided they have the event again). The engine drone from the 2.0 was a bit annoying at 70 MPH and above but it managed.
The downfall of the TH125C is when the TCC solenoid fails and makes the car buck and rock like a young horse when coming to a stop. Eventually, the engine will die and you’ll go to park or neutral to start it back up, and it’ll die immediately again once you put it back into drive.
Solution? Unplug that solenoid under the hood from the front of the transmission (losing the lockup function of the torque converter) until you can get around to replacing the solenoid itself. That’s what I did.
What a delightful pair! (I hope I can say that many times today)
I’d take the 528, the tan interior matches perfectly with the BRG. I’m driving a Focus with a PowerShift, so I’m not scared by the exabrupts of a fed up trans (I hope I’ll never have to write this again).
“I’m driving a Focus with a PowerShift…”
My condolences. Is it fixed for now? Obviously won’t stay that way…
Yes, it works perfectly, but the mechanic suggested to sell the car before the end of the year. It’s a pity, because it’s an otherwise phenomenal car.
Now, at least in Argentina, AT Focii are becoming cheaper than their MT brethren. The word was spread.
Or you could keep it and just keep fixing it. Especially if you DIY it might get to be easy and fast and cheaper than buying a new car.
FWIW: I didn’t like that transmission when I had it in press cars. Its low speed behavior is unpleasant (I also don’t like the DSG because it’s crappy in places where a regular auto is very smooth, but with the dual-clutch it’s better than the PowerShift)
This is a both day, at least at these prices. I think I would enjoy driving either of these for a few weeks. Plus, these are cheap/ugly enough I wouldn’t feel bad about sending either to the scrapyard if something non-trivial broke.
For voting purposes, I went with the 528. I really liked E39s when they were new. Had someone asked me which new car I wanted most in the late ’90s or early ’00s, I would have answered 5-series. These were a great balance of performance, luxury, and good looks. Since then I have lost interest in BMWs (mostly because I developed an interest in trucks, but also because I have never gotten over Chris Bangle’s hideous styling), but for this price it would be worth buying just to experience a car I really wanted in the past.
Either. I know the M52/M54 engines better so I’ll go with the E39 if I have to pick. The transmission sounds suspect but my experience with a lot of high mileage E46s were the same; they start to clunk or shift hard but seem to keep going. Def inspect all the plastic engine components and plan to replace a lot of them.
The E32 is one of the best-looking BMWs ever. We’ll take the 7, and use it as a canvas for our DIY painting skills.
Unreliable.
Shows 2 old cars with 300,000 (!) miles on the clock. And they still drive.
“here we have two very high-mileage examples that basically run and drive fine. Are they the outliers?”
Emphasis on “liars” Do we really think these two Beemers are trouble-free? Maybe at the moment, but how about…. now? I figure the 7-series is probably the closest to being worry-free for the moment, and it’s a better design IMHO. For that price, sure, it’s worth the gamble.
No car is trouble free. Old premium euros scare people, but they are generally cheap to buy and not that difficult to repair or maintain
Thanks Captain Obvious! I guess I should have used the “sarcasm” font for my humorous post this morning.
My sarcasm meter didn’t react either
It’s the styling of the 735 that I like best. The classic small kidney grille paired with the separate round headlights.
A quick and cheap Maaco paintjob, finished off with a wrap (so it’s smooth and clean underneath), and it would look pretty ok.
Simpler is certainly better in the world of cheap vehicles. I’ll have the 7-series.
I feel like I should go with the 7, but I have always liked the E39, and it would pair well the green/tan Accord from the other day.
The E39 is one of the best looking BMWs ever made. I’ll take that one even if I’ll have to LS swap it and make it a “race car” in the not too distant future.
I think I’ll opt for the M30 over the M52. I have nightmares of my M54 325i and all the crap I had to fix on it.
I’ll take the big one, might just splurge for and get it all to be one color.
It’s all relative, the ‘big one’ is pretty compact by today’s standards. I’m not shaming it, I prefer that. It’s just so sad what bloat has done.
The regular (non-extended) wheelbase E32 7-series actually has a shorter wheelbase than a modern 3 series, and is smaller in almost every dimension aside from length, with the E32 having slightly longer overhangs. In general, the E32 7-series and E34 5-series feel like small cars when you park them in a typical American parking lot.
I may be mistaken, but I believe the non-Steptronic GM transmissions in early E39s were four-speeds, not five.
I’ve had four E39s, so I’d probably take the 7er, just for a bit of variety, though I’d prefer an earlier E23. The M30 is a sweetheart of an engine, probably much easier to live with than the later M60 V8s (to say nothing of the V12).
E32 is so good. Not that the E39 doesn’t deserve its revered status, but the 7 is less likely to be whipped as hard.
It pretty much set the tone for the ’90s at BMW.
Older BMWs are invariably better BMWs.
7 series for me.
I’m no BMW stan, but a big beemer from that era always says “I’m the cool boss” to me.
I really love an e39, but the transmission woes make me nervous. I’d rather have the 7 series painted and fix the smaller issues.
I want the green machine and will roll the dice on the transmission needing a relatively simple fix. For only $1,900 you aren’t taking a huge risk. If it turns out that it needs a new transmission you can either walk away or start looking for a junkyard replacement.
These are cheap enough that I wouldn’t hesitate to take both, although I’d expect a whole lot more trouble out of the 1998. That one is a little newer than BMWs best years.
I like both, but the E39 speaks to me this morning so I’m going with it.
Rock, meet hard place.
The 735 is from their peak era. Give me that one all day long. It’s better looking as well.
The E39 is my favourite BMW sedan. It’s just such a great design that doesn’t age.
Simpler BMWs are better BMWs.
+1 for the Ship of Theseus reference. “But is it the same car? “
It comes with spare VINs.
