I met David Misfud hes a half chinease German Prick 1 year a ago we bought 10 quads off of them and he used to answer the phone himself at the time and had a small German outlet because I run a transport company we picked the bikes up our self. I had no problems then apart from one of the bikes was $#*! and got returned. This year i bought 10 more to sell on for christmas now it looks like i won't get them I sent someone to their old place in germany but there not there any more seems Davids moved back to china!
