Great performance.  
 Arguably the best sports sedan of its time (M5 excepted) and a classic in the making.  This car is all about driver synergy and performance.  You feel integrated with the machine: it does what you want, when you want.  Reliability is a problem:  radiator, digital displays, door seals, HVAC have all failed.  Although problems are expected four years out, I never had this much trouble with Japanese cars.  That being said, try finding a Japanese sedan that is as good to drive.  Low profile tires and sports package make for cautious parking (but I can't blame BMW for that).  Buy this car if driving experience is the priority.
