Hi,

My friend really wants to get a 750il thats between '88 and '92... and he's having trouble deciding. I have an e34 525i and i really love it but i just dont know what to tell him about the 750.. that is a HUGE car, and i also heard they are a bitch to work on.

For example, i heard that to replace the water pump it costs 1500 bucks becase its way under the engine somewhere.. is this true?? i didnt believe it...

So is the 750 a car worth getting?? is the maintenance expensive?? I do all the work myself on my car so i dont pay out the butt but i dont know anything about the 7's. Thanks !

I have a 1988 750il and these cars are getting older and of course need maintenance and that can be costly (rear LAD struts are $300 each, Brake Servo at $245) as an example. I put aside $1000 a year for maintenance (do not always need to use it). If you can do your own maintence then you can save money, but then all components are packed in tight so working room is at a minimum. Do not get me wrong, these are great cars, but very complex. Where you can touch evry engine component on a 325 or 525, heck even a 735 you can hardly get your head into the engine compatment in a 750. So, if you decide to buy a 750 get the newest version you can afford as it will be lonmger before replacements part come into play.

DO NOT DO IT

THE OLD M70 ENGINE IS NOT WHAT YOU WANT IN A HEAVY CAR

FOR V-12s YOU NEED SOMETHING WITH THE NEWER 5.4 LITRE M73 ENGINE

VERY SIGNIFICANT CHANGES OCURRED

I'm also looking at a 7 series, but am concerned about teh maintenance costs of the V12 versus an 8 or 6 cylinder. That 1200 bucks for a water pump is just what I'm afraid of.... mind you, that V12 looks great...
I'm looking at the older models 89-91. Any concerns? Any thoughts.
Also, how do BMWs stand up after 120k miles. Are they a good high mileage car?

Thanks.

The newer the better (1988-1992), but these cars do hold up well. I own a 1988 750il (they are all il) and the engine uses no oil between changes (annually). I must reiterate that as with any car, as they age they will need replacement parts. Shocks or struts, belts and hoses, brakes, brake rotors, tires, battery, fan clutch, control arm bushings (to state a few). As to a water pump, you can buy OEM pump online for $200 or less and installation is not difficult as the pump is on the fron of the engine just behind the fan. You must remove the fan assembly (maybe five minutes) and remove the belts and then it is a straight forward pull the pump housing and the pump, replace the pump and gasket and you are in business. If cost of repairs is a consideration, then the big six in the 735i might be better for you. Also the il versions have either LAD (hydraulic damping rear struts) or EDC (electronic dampening struts) and replacement of thes is pricey (I just replaced a rear LAD strut on my car and the online price was $385 for one. Remember this is after 17 years). I did convert the AC in mine to HFC 134a a few years ago and it cost me $700, this was a new receiver/dryer, expansion valve, evaporator and all "O" ring seals. I kept the original compressor and the system will freeze your knuckles. Hope this helps and do not hesitate to Email me with questions, I do not mind answering them.

Thanks Bubba,
It sounds like they're not too bad to work on. I remember teh old Jag V12s (late 70s) where you had to take half the engine out just to reach teh spark plugs.... or so I was told. As for teh struts, I'll make sure they were just replaced on teh car I buy or nego the cost out...hehehe.
Do you know about their performance vs teh V8 or V6? I know something about engines but not much about BMWs or V12s. Are they reliable? Do they have a broader torque band? Are they quicker (0- 60)? why would someone choose one engine over another?

Thanks again,

Per aka BMWDAD...(well soon to be anyway.. bimmer that is)

The V12 is really tight in the engine compartment, and the plugs are tough to get at but can be done. The I-6 is a tough engine, perhaps the best six BMW ever built, 0-60 run in the 7.1 for the manual transmission and around 9.0 seconds for the automatic (ZF4HP22). The V8 is of course quicker and thirstier but not quite as quick as the V12 (0-60 in economy moe at 7.1 seconds and in Sport Mode at 6.4 seconds. All of the engines we are discussing are electronically goverend at 155 MPH). If you go with a V8, be awre of the NIKASIL issue in the 1994-1995 models (high suphur content fuel problem, see koalamotorsport website for moe info).

For reliability overall the big six is probably your best bet, for a great autobahn cruiser, the V12, and the V8 lies somewhere in between. Check this website for good how to on the engines you are looking at.

Thanks for the advice. I had read about the Nikasil issue in one of the other forums here. I'm looking at the 89-92 models so it won't be a problem.

The link you gave was great. The first article I looked at was ironically about replacing sparkplug #12... it looked tough, but they said it wasn't. Mind you 30 minutes on one plug... oh well, I'll be going 0- 60 more often than I change the plugs.

Know anyone who's selling a 7? Anything I should look for in particular with this year and series?

Thanks again,

Per

I do not know where you live, but I live in S.E. VA and my tech has several 7s for sale (I just sold a 1973 2002tii). Have you tried the ROADFLY site or AUTO TRADER.

I'm in N.W. CA... just a mile or so west of you.:O)

I'm actually in San Jose but looking for something just a little closer. I've seen some stuff on Auto trader and cars.com, but I'll try Roadfly. I was surprised the local BMW club didn't have a bigger classified section. Typically you get well maintained cars at a fair price. I'll try the LA chapter as well.

Thanks,

ghead
I am doing a 1990 750IL
at frist found one that didn't run for 1000 bucks, had 149923 miles on it,
here is what was found on this one some how someone had sourted out the battery jumping post that blow out the in line fuse to battery, what that did is knock out the power to DME's and Fuel pumps, Of course fixed that and found that the trans was burned up, got to be the smelliest thing ever, pulled the trans, got a friction plates kit $205.92, seal kit $125.40, and 6 steel plates $21.89 rebult it myself save me $1000.00 bucks on laber. I found the drive line needs to be replaced at this milage do to front u-joint. Don't try to do this one, just get a new drive line $400.00, I have seen it listed for $1000.00. Replaced front strunts BOGE's $146.00.

I must say this car ride really good now, and it is a fast one at that. the chip in this one is set to 110 mph.

I have a 86 735i, and it has 227 thousand + miles on it now. It sat for 18 months, and it turned right over with a new battery and sparkplugs with a new fuel filter as well. The 3.5 liter in line six was a great engine, and it would be more reliable for you (the same engine was carried into the newer model 7 series, 88-92 I think. Good luck finding the car your looking for!
