The Opel Adam is more of a 500 copy then the smart. It just has a 2 tone roof. It competes against the Mini, and 500. The Tridon didn't really work on the old 4 door smart. That was a really ugly car. The 2 tone works on the 2 door smart. Too busy on that concept drawing.That's Smart's benchmark, now even sort of copied by the Opel Adam and Audi A1. so that feature will stay...
