This is more difficult than it ought to 
 Wonderful tossible car, great engine.  There are some inherent design problems, i.e. the shock mounts, lack of cross bracing, an awful cd/radio system, a plastic rear window, and an off center steering wheel.  It is a strong solid perfomer nonetheless and I think, though not as good a car as the z4, it is a hell of a lot more interesting.
