Went to test drive a roadster GXP yesterday at a dealer. Car was red with 51K milles. The problem was they couldn't get the top up. It went down fine but could never raise it. The saleman called a 'tech' out to help and he couldn't figure it out either. The problem was when the top was raised it was about 4 inches too short from latching onto the windshield. The windows were down and no obstructions were obvious. So I'm wondering if this is a common problem in the Solstice where with age the top becomes a real problem to reattach. Thoughts?
