128i Convertible
 I went from a Z4 to the 128i convertible and from manual to automatic transmission so there was an adjustment in expectations. Overall, I have been very happy with the 128. The build quality is outstanding. The handling is exceptional and the motor has plenty of punch, especially in manual shift mode. I love the way the car learns your driving style. The only negative is the standard sound system (not the premium pkg). Speaker placement makes it virtually inaudible with the top down at freeway speeds. The Z4 was better probably because the speakers were directly behind the seat.
