Thought about a Z3 once, but...
1) Not enough leg room (knees hit the dash)
2) Not enough head room (perma-crick in neck)
3) Sill too high (knees in chest when egressing)
Near as I can tell, the car is made for people from about 5'8' and shorter.
Same situation with the Jaguar XK8. Really think it is one of the most beautiful cars on the road today.
