2003 BMW Z4 Convertible 2.5i 2dr Roadster (2.5L 6cyl 5M)
Needs improvement
 Owned the car since 2004 has now 82,000 miles, performed well under warranty, had to replace the motor for the convertible top at 42,000 mi and now again at 82,000. both times the elec. motor short circuit due to run off  water  that enters  the plastic housing where the elec. motor sits in. The water can't drain and the electr. motor will rust and quit. Very expensive repair, poor design.  Car handles great, fun to drive on smooth roads but noisy, and potholes are deadly and my wife hates to put on her make-up while we are driving, rough ride
