I bought the car some months ago and had to replace brake pads, and one trailing arm. Parts can be expensive, but if the car is in good shape, you don't have to replace many.
A/C works great at night, during the day is not enough. Transmission makes some annoying 'noises'.
I love it. It's old but makes you feel great when you are behind the wheel. I will only replace it for a newer one, and hopefully I won't need to sell it to buy a newer one.
Next one: 325is E36! (328 and M3 absolutely out of my budget).
To fix the trans noises you gotta get a 17 millimeter allen wrench take the fill plug out and PUT IN FLUID!!!
