Unless there are things about the 535 you currently own that you are worried about in the near future, I would stick with the devil you know.

Regarding the items you note on the 525 -

Temperature fluctuation - sounds like the Tstat is stuck open - that is at least one thing to fix. Keep in mind that many M50's loose their original water pumps (the plastic impeller kind) around 65-75K miles. If it hasn't already been swapped to a new, metal impeller pump, you should change the water pump at the same time. What the hell, for another $200 if you don't have a good record of the previous owner's anti-freeze changes, throw in a new radiator for good measure.

There were notes regarding some slapping noise from the dash area at certain speeds a few weeks ago, was eventually tracked down (I think) to some of the panels under the windshield edge of the hood that were a bit loose. Is this the sort of turbulence-created noise you hear?

Do you mean the door panels are coming off the doors, or that there is cosmetic damage due to the breakdown of the adhesive on the door panel? I have a Florida car with this problem. It ain't pretty, but the doors will work fine until I track down some new panels.

How much do you need to play with that Auto/Manual button anyway? There have been posts regarding the trans getting stuck in manual mode, then resetting with a power cycle. If the trans is strong, it shouldn't be a problem.

The M50 motor is a timing chain with automatic tensioners that (under normal circunstances) never needs changing or adjusting. The valves are also self adjusting, so you would be getting a car with less intensive regular maintenance routines.

'92 525iTa, 93K, perfect health!

A while back I requested information about the 1992 525iA. My neighbors mother is selling her ex-husbands Maroon 525 with approx. 73,365 miles, he was the 2nd owner, purchased from a BMW Dealer about 4yrs ago for $9,500 neg. I was able to see the car today and these are a few things I noticed:(1)Needs front shocks/maybe rear (2)When idiling the thermostat reads at the middle, but when driving the needle stays at 1/4,then returns to middle when at idle (3)Noise comimg from Guage Console when at 80-90mph (4)The automatic/manuel button worked when engaged, but after using it multiple times it would not engage. I had to shut the car off and I guess it reset the system??? (5)Both rear door panels are about to pull off (6)Not sure if the timing belt has been changed. What mileage should it be changed? and (7)The handle for the steering wheel tilt is broken off. Otherwise the engine sounds great and the tranny seems to shift smoothly. Can anyone diagnose these problems? Is the car worth it, as far as price and overall reliability? I currently own a 1990 535iA with 108k and had the head gasket done already, plus suspension (need new front shocks). Do you think I should replace my 535 with the 525? What would be a reasonable offer?
