I've only owned mine for a year and put around 19k on it but it's been a free ride so far. I have the 5 spd. Agree with someone else who complained it's not the easiest to drive smoothly but no complaints otherwise. I love the reliability (nothing has failed) and quality of materials/workmanship. It gets around 28 mpg and has plenty of power. Third gear is my favorite - it just keeps pulling. Suspension is a little soft - it doesn't track like my old 318i or GTI but sure is nice on the highway. I plan to drive it a long time.
Engine, moonroof, Bose stereo, front end styling.
Tighten suspension a little. I also find the seating position a little odd - the pedals are too far away relative to the steering wheel. Clutch is going and I've heard that this isn't unusual at this mileage. I think this could be improved.
