2011 BMW Z4 Convertible sDrive30i 2dr Convertible (3.0L 6cyl 6M)
Too many repairs
 Front struts, valve cover gasket, tranmisssion seal, front end grouments all needed replacement at 25,000 miles. Has issues with vibration in convertable top also. Both rear rims cracked due to poor manufacturer process. Too costly to drive.
