I'm looking at used BMW 335's for my girlfriend's new car. We found a good one, but the carfax says it had a right side impact 3 years ago. Is there any way of telling how bad it was? As far as I know, right side impact could be anything from a stray cart in a parking lot, to getting T-boned at an intersection. The only reason I'm concerned is because it is a hardtop convertible, and I don't want any issues with the top sealing/closing.
