03-04 Z4

Hey everyone. This is my first post. Im thinking about getting a 03-04 Z4. The thing is Ive been reading everyones problems that they have had or still have with their Z4. Do a majority of these cars have these problems? If so...are they fixed or do you still have the problems? I have heard great reviews on the drive quality of this vehicle. Im going to go test drive one on Monday to see how I like it. Please leave some info for me and other Z4 enthusiasts. Thank you much!
