2004 BMW 3 Series 325i Rwd 4dr Sedan (2.5L 6cyl 5M)
I purchased the vehicle new to replace a 318i that I loved and drove for 8 years. This car has been a nightmare. First, the dealership messed up the installation of the BlueTooth. Then the engine wouldn't start, and the car, which was less than one years old, had to be towed in for service. It took one week to repair! Then the car needed brake service. And the turn signals have never worked properly, nor the door locks, even after multiple servicing.
Body design & color (mine is red).
Improve quality control and/or improve the electrical components of the car, since this continues to be the problem in my case. Really disappointing for a BMW.
