Hi, my name is Sara and I recently purchased a 2005 Roadster limited with manual transmission and lots of problems. So far we have 3200 in repairs and it is still at the dealership. New key can't lock or unlock doors. New tires still vibrate vigorously at 55 mph among other issues. Very frustrating. Any suggestiins or ideas would be most welcome. Dealer clueless. In fact, I directed him to this forum hoping he could find some answers. Thanks in advance. Sara in Florida
