I was surprised how quiet the Copen was with the roof down. Today I took it out for the first time with the roof up, totally different story! The roads in Thailand are mostly not good, especially the small town I live in. The front roof hinges make a lot of noise. The passenger one doesn't seem to lock down properly and constantly rattles and the drivers side doesn't rattle but pops open a bit when I go over a bumpy stretch of road. There's also some rattling behind me but it was busy in town and I was on my own so I couldn't determine what that is yet. Any fixes for the front hinges not snapping closed ?
