Has anyone driven/owned an 88-94 BMW 750

[elwesso]

I know, so before the flaming starts, Id like some info..... Then you can flame all you want.......

Id be looking at the 12cy, not the 8cy, since in 95 it had problems with the block.......

So how do they match up to the Q....? Probably not even close in reliability, but what about the other stuff.......?

[Jesda]

Youre correct, not even close in reliability, but honestly not bad either. Maintenance expenses, due to parts, will be rather high, but not impossible. A large number of owners have kept theirs since day one, with expenditures mostly on preventative maintenance. Like the Q, keep it running well, dont slack off on anything or let anything fall apart, and you'll have a somewhat trouble free cream puff.

They also eat tires like a child with a bag of halloween candy. But thats inevitable on a large performance sedan.

The driving experience is said to be fantastic, dreamy, handles like its on rails, with nifty luxury features like rear mirrors that tilt when you drive in reverse.

Expect 12-15mpg, fillups on a 26 gallon tank, and smiles for miles.

[Jesda]

Oh, and the first year of ownership on a used example with 100k can cost you $4000-$8000, just like the Q.

[elwesso]

FYI-- The Mirrors do that little thing on the Q.......

[Rex]

You just have to have the power mirror adjustment knob turned to either the right or the left mirror. Having it in the middle "non" position, defeats this feature.

[elwesso]

On mine, you must turn it there after youve put it in reverse at least once....... Also, you must program it to do so.....

[elwesso]

Does anyone know the common problems on the 750s.......?

[Rex]

Here's a little on performance and maintenance

http://www.digest.net/bmw/archive/v8/msg00122.html

[elwesso]

They dont really sound much better or worse than the Qs....... Except for maintenance........

Is there a car out there in the same year range (90-96) that outperformes the Q in performance and reliability......?

[elwesso]

I did a little research, and the ONLY car I could come up with comparitively is the cadillac seville....... Do you think that the Q would be able to handle the STS??

There's a red STS on a lot near my school, and everytime I go by it yells at me.....! I already know about the northstar and all the crap that goes with that (I probably know more about the cadillacs than I do the car I own!!!)

[nuQ]

wes, it really seems like your looking for an excuse to get rid of the Q,,,,,or, are you looking for a second car?!!!! with all the time and money you've spent recently, i'd assume it's for a second car...............LOL jeff

[elwesso]

No...... Im ALWAYS looking....... It doesnt matter if its golf clubs or cars, Im always looking.......

And these sorts of questions are to see if I have what I really want........

I know that Id probably regret it if I got rid of the Q, and its so very close to being perfect (new suspension, and all maintenance items, all it needs is knock sensors, a plenum cleaning, some new leather on the front seat bottoms, and Id like some Q45 floor mats), id probably be stupid to get rid of it......

But....... has anyone raced a Q against a STS or ETC??? Id be <really> interested to see how well they hold up against them....... How about other cars, like GTPs, mustangs (GT), etc........

[elwesso]

And if I did get rid of it, it would go to <only> a NICO member.........

[Jesda]

What? My 92Q can do the automatic mirror adjustment on reverse? How? Or is this just a 94+ thing?

[elwesso]

Yeah...... Your 92 can do it.......

Email me..... Ill give you the procedure..... Or you could search........ Its really simple......

[Q45tech]

Really in the early -mid 90's every body [4 doors] had the 4 speed AT till 97-98 - that's what improved the acceleration times. The ZF 5 speed AT set the standard in BMW and MB.....SL500.

The Q modeled the BMW as the standard, they tried to find a balance at half the cost.......remember the Q launched at $38,000 in 1989 vs almost $68k for the 750il, heck the BMW 735 6 cylinder was $50k equally equipt.

Not many [same class] cars can beat the early Q from 55>80-85 mph. The modern 5 speeds lose because of the 65-70-75 mph shift.

[elwesso]

Is the 750 one that can beat the Q??? It has like 300hp (?) but its quite a bit heavier.......

[1qckser]

Can the 91 do it also? The mirror trick, that way my wife would never scuff my tires while parking again.

[Q45tech]

The V12 was low tech 2 valves per cylinder 5 liter all aluminum, delivering 333 lb/ft and 300 HP. The zero to 62 mph was 7.4 seconds.

"But nevertheless these cars apparently weren't designed to last over 10 years, the car keeps breaking up at least once-twice a month. Even though none of the problems have left me on the side of the road, the astronomical cost of parts make it very difficult even for a DIY enthusiast to cope with the costs. I would have a lot better use for my time and especially for my money.

I've spent 5000 euros[ $6,000 US] this year in parts while trying to fix the car at a faster pace than it breaks up and yet it's currently at the transmission shop. "

Check out the cost of a remanned 4HP24-Special transmission

And members whine when I tell them a Q needs a measely $3,000 per year.

Didn't the reverse tilt side mirrors begin in 1994 Q?

[elwesso]

Im pretty sure you can do it on the 90-93......

If all else fails, you could always try programming it...... heres the procedure

1. Apply P-brake2. Turn ignition to on (not started)3. Put in reverse4. Turn the mirror selector to either L or R5. Adjust the mirror so its where youd want it in the back up.6. Press set, and then select the number7. repeat for the other side.....

Thing is, it wont turn down every time, you must select which side you want down, and then it will....... I like it this way better, since on our suburban, it can do it every time and it gets annoying.......

[szh]

with nifty luxury features like rear mirrors that tilt when you drive in reverse.

The 1995 Q45 has these too!

[1qckser]

I just tried it and no luck, I think its the 94 that does it, ant more info would be great thanks.

[suretytek]

Do the 97-01 Qs do this as well?

[elwesso]

I wouldnt understand why they wouldnt...... You can goto http://www.infiniti-techinfo.com and download an owners manual for free if you dont have one..... it has the procedure for programming in there (if it has it)....

Now..... back on topic.....

It seems to me that the Q is MUCH simpler than other cars of similar year and class...... For instance, the cadillacs with the northstar have this nifty OBD that displays a ton of codes, in easy to read digital format..... Why doesnt the Q have this??? I mean, they could display codes via the driver info center.... What gives???

[maxnix]

Do the 97-01 Qs do this as well?

That's a good question. I have not been able to discover it in the owner's manual of my wife's 2000, nor have I been able to replicate it on her car.

I can't believe Nissan would delete this feature when they added a quite a few others to the generation II Q45. Power headrests I can live without, but the reversing mirror feature is a real wheel saver, especially on high curbs.

[Bubba1]

I've ridden in one, but not have not driven one. Wonderful and smooth. Very refined. You can always compare stats, but the ownership experience is sets them apart. It's like comparing a Rolls to a Lincoln Town Car. Sure they're both comfortable, have similar options and perform similarly. The real difference is cost of ownership and repair. The V12 is exotic (translation: not for the light walleted) It will shock you how pricey V12 Bimmers are to repair. You'd also be surprised how unreliable they are, despite being so expensive new. You don't hear much about big bimmers with 200K miles on them. It may be the "ultimate driving machine" but you need an ultimate bank account to maintain it correctly. I'd stick with a Q. Less prestige, but same performance, better value, and less expensive to keep. V-12 Bimmers are more for being seen in, not for daily drivers.

[suretytek]

maxnix,

I haven't been able to find it in the service manuals as well. Q45tech, is this a feature that Infiniti deleted on the 2nd generation Q?

[AREITU]

On the contrary, there's an article in a car magazine...I don't remember what exactly, but it mentioned the 750iL as a good used car. It's all about the regular maintainence. If you're willing to front up the money for that, and 14 miles per gallon for premium fuel, nothing beats a V12. A friend of mine had a V12 Jaguar and it was the epitome of automotive excellence. One has not lived until he or she has heard and experienced a V12 in person. It was smoother than a baby's *** and made sounds that I could record and listen to over and over.

Maybe so, but to reitereate Q45tech's statement, these are low tech V-12s with SOHC and two valves per cylinder. V-12s are smooth because of the primary balance (at 120, 60, or 180 degee cylinder bank spacing) and even power, but they are not necessarily current technology showcases.

The later Ferrari's (always at the forefront of the current technology), Lamborghini's (Countach on, but like Ferrari, always on the current cutting edge), and the last MB generation (DOHC, 4 valves, not the current 3-valve SOHC one) are much more modern designs.__________________Brian1995 Q45 & Q45t

If you read my post carefully, I never said it was a technological showcase. If you're concerned over how many cams and how many valves per cylinder they actuate, you might want to stick with the Q. Nevertheless, the new BMW V12 dosen't have throttle bodies and uses direct injection. Just wait for that one to depreciate. Note that Ferrari no longer uses a five-valve pentroof combustion chamber in their V12 on the Enzo. The F50 had a five valve combustion chamber. But the Enzo produces more power and torque with less valves. Same manufacturer...same engine...I wonder why? Benz's reason for going back to three-valve is justified. A single exhaust valve absorbs less heat than two, leading to quicker catylitic converter light-off. They also have two spark plugs per cylinder wihch leads to cleaner combustion and less emissions.
