My '00 GT (60,000 miles) top comes up at an angle at first, as if the drivers side is not powered properly. Once up about 2 feet, it levels out and all is fine. Dropping it is fine. This is the same on a friends '01 V6. Any suggestions? Did a search and found nothing relating.
The problem is that one of the cables inside the top rails that makes the top move has stretched. You will need to take the car to a convertible top shop and have the cables re-adjusted. It should not be very expensive. My GT was always like that, I just lived with it...
