View Full Version : Advice on buying 06-07 750 What do you wish you knew?

09-20-2012, 07:53 PM
I a multi-BMW owner and my current car is a E39. A couple things I knew before I bought it was that at 100k I was going to end up replacing the entire cooling system and I would never want tan interior again......:thumbdwn:

I'm likely to end up with a 750 with 80-100k on the clock this time but I'm wondering if there is anything I need to know or might regret no knowing.:confused:

What do you wish you knew then that you know now?

Thank you for your support :thumbup:

Warranty = :thumbup:

No warranty = :thumbdwn:

BUT when getting a car with that many miles, it's hard to find any decently priced warranty coverage. With that said, if you are a DIYer, you'll love this car - as you'll probably have a new project every few months :rofl:

Common problems include: Transmission jerking when shifting from 1st to 2nd gear, a weep hole coolant leak (may or may not have been fixed in 06 and greater models - someone chime in!), and faulty Logic 7 amps that have a mind of their own.

Of course there are more things that slipped my mind but others will tell you!

Other random problems I've had since I bought the car in 2008: front left window actuator, sunshades get stuck (very easy DIY fix), brake recall (should be replaced for free), cylinder misfire (BMW said it was due to bad gas), faulty CD changer, faulty trunk hydraulics

BUT even with all that said, we all love our 7's and I wouldn't choose anything else :D They have the perfect balance of luxury and driving dynamics

YES E39's too. I've fixed all 4 window actuator's more than once each in 9 years of ownership. They are crap. Trunk hydraulic as well but only once.

Crossover coolant pipe
Light control module
Control arm bushings
Spark plugs
CCV valves
Water pump
Most network Problems
Ask unit
L7 amp
Secondary fan
Final stage resistor

Need to replace a squeaky AC fan.

All within the last year replaced.

Problems I foresee happening at some point.

Valve chain guides
Carbon buildup
Valve stem seals
02 problems
Brakes and rotors

My transmission was replaced at 20,000 miles, the one in the car shifts hard, done the transmission oil change last year, need to do the guibo joint, matronics, ect, ect, ect

Don't forget the seat sensor mat, multiple error codes, and stuff just getting old.

the guys really dumped the brick on you! :)
these cars are pretty expensive to maintain and fix i'll give you that, while doing a DIY on the ASK, a single spark on a loose wire cost me around 2K to fix! then there's the labour! due to the complexity of these cars, its really hard to find someone who will fix them for reasonable prices even for my country ( i'm in a country that supposedly has cheap labour! :p )

but that being said....i would have to add that the pleasure you get from driving a 7 is not matched by any other other car..i've driven audis and mercs...even the 5 series. somehow the 7 always manages to draw a big f***ing smile on ur face :D
the best thing i like about this car is how u can cruise at 200kph and not realise it...how u can take 40 degree bends and not even feel the Gforces...and the acceleration is is incredible..the engine outputs great power all over the range and i have a 735! imagine what a 750 would do! :)

do keep in mind though...this is not a town car, its a long distance cruiser, u wont feel the benefits of this car unless u regularly travel long distances...mine does around 7k km a month!

so if you commute to work and dont mind doing stuff urself this is the ride for you :)
