Arguably the most comfortable performance sedan ever built. Nice clean lines. Buy it right but set several thousand aside for initial remediation. I replaced water pump, window motor, control arm bushings, right cat, headlight lenses, and tires in the first year. Had leather refinished to like-new last year. You can get good quality non-BMW aftermarket parts drop shipped to your independent mechanic and save big $$$$. All-in I probably put 4K into the car since purchase bringing total cost to less than 11K. I get 22 mpg highway driving aggressively, 24 otherwise.
The seats are amazing! Almost six hours without getting out of the car and no back fatigue at all (and I am nearing retirement age). The trunk is huge. Acceleration is smooth and fast and the engine has plenty of reserve power.
The stereo is great but setting it up the way you like it will take a little time.
