Yeah, reading through that list...it becomes apparent that this guy is the "put gas in it and steer" type. From that repair history, it seems that car hasn't had any PM in the entire time he owned it - he just waited for stuff to break. :(

But can 4 radiator replacements in 4 years really be excused?

Something tells me that (and probably many of those repairs) is the result of the dealer seeing that guy coming a mile away, and doing what stealerships do best. I have a feeling 2 of those radiators were completely unnecessary, and just thrown in by the dealer to pad their payout. Look at this guy's repair history. Complete mechanical retardation? Check. History of writing a blank check to dealer for work done in the past? Check. They probably threw every part that could even be remotely related to the apparent problem they could find at it every time this guy came in the door because they knew he'd pay up without asking questions. He never knew the difference because he isn't savvy enough to even begin to figure any of this poo poo out on his own. Dealers love customers like this.

Even if all of those radiators were necessary, the fact that he went through four of them would indicate either him getting defective parts (not the car's fault), or some other undiagnosed issue that was causing premature failure of the radiators. Maybe a bad radiator cap or head gasket causing overpressure, etc.

Which in fact there was -- a recall on a drat radiator cap!
I know the guy bought a 17 year-old top of the line luxury car, but I can understand to some degree that he wouldn't expect certain things to go wrong with it, like the windshield seal coming out on the highway, or the control module malfunctioning. Even if the dealership was taking him for a ride, there were pervasive issues that they couldn't fix.

In a word: unreliable. Probably one of the most unreliable BMWs ever made. The motors and drivetrains are tough, but everything else falls apart around them. Check out this site for one guys story: http://my750.com/mystory.htm

I suppose if you have something else to drive, it wouldn't be as bad. But you'd still be dumping money into a car that wouldn't ever be worth very much. You'd have to really love the body style to justify the expense. The E23 7-Series is much better even though it's older. It's also (IMHO) better looking.

Huh? An E32 is pretty much an E34, and I wouldn't classify those as unreliable. I'm pretty certain the fundamentals of the M70 engine (block, heads, etc.) are solid, although I'm sure the engine electronics and related parts might be quirky and will give more problems than an I6.

I also agree with Black88GTA, looks like the guy paid for 100% original parts ($$$$$) and at high-priced repair shop that charged extra just because it was a 750. If you can do the work yourself, and have more patience to diagnose faults so you don't replace stuff unnecessarily, you can do it for a fraction of what he paid.

All in all, in my opinion, it's just a bad idea to own an old car with such advanced levels of equipment and options if you can't work on them yourself.

I certainly want to own a V12 one day, just because, and I wouldn't be afraid of an E32 750. It is though, to be reasonable and economical, pointless if you're looking for performance and large-engine feel, because you can get an E34 540 with a 286hp V8, in a car that weighs less, instead of an E32 750 with a 300hp V12. But hey, V12!!!

I will agree that this guy's experience is extreme, but the E32 750i was not a reliable car by any stretch. Mike Miller (tech writer for Roundel and Bimmer) describes them as "mechanics cars" meaning you should be a dealer tech if you're considering owning one. They are indeed like an E34, but the E32 came out before the E34 and was kind of a "first generation" version of it. Most of the electrical bugs in the E32 were solved by the time the E34 came out. Can you find a reliable E32? Yes. The 735i with a manual (rare in the US) is a good example. All the electricals might not work, but the car will start and run forever as long as you change the oil.

I agree with this guy. When I was looking for a BMW I checked out a 750iL that was in good shape and I really liked it until I hit the gas. Smooth as silk but I couldn't stand that gas mileage for something that is slower and harder to handle than a new Corrola.

I'll agree with it's bad handling, but it certainly shouldn't have felt slow. I had an E32 740il, and that thing was quicker than balls.Luckily, I sold it to get my current E46, and two weeks later the Trans light came on in the E32. I felt bad for the guy, but luckily it was a failed resistor of some sort in the tranny.

The onyl problem that car ever gave me was the rear intake manifold plate gasket going. It dumps oils into the engine, and makes you think you've blown a ring or something if you're not aware of this plate. $40 bucks and 6 hours later, never had a motor problem until the day I sold it.

Depends on where you live, a Corolla in Europe is a slow economy car and will get stomped by any V8 or V12 BMW. There is absolutely no "regular" car in Europe that does 0-60 in less than 9 seconds, and most people buy 11s+ ones with an <1.6l engine. Anything above 1.8l these days is considered a bit exotic, and anything from 3.0l and up will have people drop their jaws, at least here in lovely Denmark, and we're a pretty wealthy country too.

And quite frankly, who cares about gas mileage when you're buying a V8 or V12. I'm honestly a bit tired of even hearing about gas mileage as a complaint when talking about these cars. I get 7-10 city MPG in my 540 and I just don't give a drat, floor it every chance I get :).

I think the biggest reason not to go with the 750 over a 740 or a 540 or something is because the V12 is a lot more complicated/parts are a lot more expensive and gets what? 15 more horsepower or something in the passenger car trim?

M3 are the best cars ever made. You should look into detailing the hell out of that thing or learning how. Headlights would look so much better with a quick wet sand.

Also like how your car is so bad rear end it knocks cones over before it gets to them. :) (Never autocrossed so I have no idea what is up with those.)

I figure E85s are too new to be in any junkyards, but they have to go somewhere when they're totalled out, right? Maybe check Bavarian Auto Recyclers (though I hear they don't have a good reputation) or places similar to that.

Hell yeah, love the M3's.

The car has definitely been driven hard for many years. I'm not too worried about making it showroom quality, or car-show-winning-clean. I bought this car to drive. And drive it I shall. I still have my GTI that's nice and clean and low and slow. I claybarred and waxed it about 2-3 weeks ago and all that did was show off how dinged up it really was. haha. Maybe someday I'll clean the lights or get new ones but it'd look kind of weird to me having a dinged up, dirty black car with nice clean shiny headlights.

totally busted out a fog light that day at the autocross too. Nailed a cone then heard a dragging sound. Thought I was dragging a cone, turned out it was my passenger side fog light. Guess it happens often in these cars. I'll pick up some fog covers and zip tie 'em in that way I don't have to worry about it happening again. Cause they'll get beat to hell in winter too.

With all the cones I hit at that event I'm sure all the other cones were scared of me so they laid down in fear!

Those ones are pointer cones showing where to go, so they're supposed to be like that.

It seems my LCAB is torn.

Here's the problem: I bought these from RMeuropean.com and had a dealership install them. I tried and failed but that was on the passenger side. I never touched the driver side. Either the parts are defective or the dealership messed them up somehow or never installed the new one on this side. The control arms on this side definitely were replaced, however. Bushings were OEM brand.

How should I approach this? I brought the parts to the dealer so they're going to say it was bad parts, but if this is the case could I get rmeuropean to reimburse me for parts and labor?

It's crossed my mind, though I don't know how difficult the job is on a Z4. It looks pretty straight forward on the E46 M3, but that's a different layout and an SMGII.

My absolute cheapest option seems to be a $400 rebuild kit from BMW and DIY. I'm still fighting the warranty company though, so hopefully it doesn't come down to that.

~23-24 in the city, as high as 32 on the highway (calculated, not going by the OBC).

In combined city/highway driving my OBC usually reads 26.4.

Intake boot, fuel lines, fuel filter are all less than a year old. I hear the pump whirring away. These are words of encouragement for it being fuel related though. Is it possible to still have a distinct smell of gas and foglike exhaust if it's not getting fuel correctly?


I'm going to try this next. I just checked all of my ignition wiring for correct resistance, that's all within spec as well so this is the only thing left to try. My friend suggested a website that sells a set of six, professionally rebuilt, and tested injectors for $70?

1985 e30 325e

As a follow-up, I ended up fixing the problem finally. I believe it to be a combination of the fuel-injectors being dirty and faulty Oxygen sensor readings. I got my injectors back and the can ran much better, but now it only missed after getting warmed up.

For the heck of it, I unplugged my oxygen sensor from the engine bay this time and the car has been running perfect since. Rockauto.com has replacement sensors for about $20-25.

On the other hand I just picked up an e36 93' 325i for $1300 with a toast clutch.

The clutch isn't what I'm curious about. It's the outside temperature sensor. The sensor was missing completely and I got a new one and connected it to a brwn/orange stripe and brwn/blue stripe wires dangling above where the driver brake duct was supposed to be.

The car still doesn't read above -35, even with shorting these two wires directly. What would cause this? Where does this wire go, to the OBC directly? I also have the cold weather package, but that temperature sensor (passenger side) is of a completely different style. Could that sensor throw it off?

Mixed city/country/highway driving, actually. This was calculated at the pump. I put 255 miles on it and the tank took 9.519 gallons after a top-off (26.78mpg after topping off). I don't feel like I am pussyfooting around, either. I had several days where I ripped through the gears because my son wanted to know how fast the car is (he's 4 years old).

Similar car, I was getting 22-24 mpg for the past couple of years that I owned it. Put some redline fuel injector cleaner in there and I got 27. I figured it was a fluke, but I have not used the injector cleaner since then and for the past two fill-ups I have calculated 26mpg.
