2007 BMW 3 Series 335i 2dr Convertible (3.0L 6cyl Turbo 6M)
I had Infiniti G35 before and hesitated getting a BMW because of poor reliability track record of any new BMW models. The car looks beautiful and drives well, so I listened to recommendations and bought the 335 hardtop convertible. In the 2nd week, the hardtop started to slam down when closing and doesn't tighten. I took it back and it's been 4 days and I still don't have my car back. Comfort access features, navigation, and iDrive also have some bugs. While I like the car when it's working right, I don't think it's worth the hassle. It's been the worst experience with any car purchase across the board.
Retractible hardtop when it's working. Handling when car is not in the shop.
