The only real problems I've had were cold weather related power issues. Oh, and one time my water pump exploded and I had to replace that, and I replaced a wheel bearing and heater switch. Also some window bracket greasing etc. One time my power steering/brakes failed and as I was driving home from the insurance place after uninsuring it (was going traveling for a few months) it magically came back, and has been back for 2 years since.
Point is, I don't have the time or money to have as beautiful of a car as most of you do (I find time to look at all the eye candy i can though), but I've managed to keep it running and have learned a lot in the process. A relative gave me these wheels that he had from an old E28. It's the first cosmetic thing I've done to my car. I know my license plate is bent... it's not properly installed and got dinged in the car wash.
