Well, I´m not an experienced BMW-owner myself. I just bought my ´91 750iL mid March. But I think these cars are very reliable. Check the following items like I did;
1) Check for vibration around 50-55mph, also when braking.
2) Does the automatic perform gentle shifts in E(conomy) mode? Does Sport and Manual work well too? (drive around in Sport-mode until the car gets warm as mine acted a little up when it got warm at first).
3) Has the coolant cap been replaced with a newer one? The older ones didn´t let out steam well and the result were the heater-radiator could blow inside the car. The new type has a text on the cap, but the older ones were just plain blank. It´s located in the middle of the engineroom on the torpedowall. Easy to spot.
4) Does it accelerate cleanly throught the whole RPM-range?
5) Brakepedal is firm and even?
6) All the electric works? Board computer, lights and interior lighting? What does the green/yellow/red servicelights say? More green is more recent serviced. Though since the guy is a mecanic he could have recently reset it himself of course.
7) Check all other electric stuff (seats front, rear), sunroof, windows, heated seats etc.
As for the AC, I´ve just heard that the controls in the car can act up a bit. But this is a fairly easy fix.
I´d recommend these cars to anyone, especially if you can do some light fixing yourself. Like you said, it can be costly to fix in the shop.
The driveshaft was just recently discussed on this board, a bit down on the list. If your´s is worn you should notice some vibrations around 1500-2000RPM I think. My car has 191000km (120000 miles) on it and runs like a charm.
The E23, E32 and E38 refers to the different yearage/models of the 7-series. E23 is the pre 88 models, E32 is 88 through 94, E38 is the latest 95 to current. A new 7-series is expected this fall I´ve heard. Seen some preview pictures, and I think it is the E65...
As for rust. I´ve not seen a bit on mine. I think they are well covered and don´t rust much.
