Although the Opel Adam is a nice looking little car, I can’t see that being the one. For starters it began production last year, so there would be no reason to keep a secret they were going to make one. Plus, the roof would have to be made as a separate piece to the body. Too many parts for current production methods (which sucks). I always liked those models with the separate roof piece. It gave something more to them rather than just a one piece body part.
