Interesting to hear your thoughts - good review. What worries me about going from a 3 coupe to a 1 coupe is that you don't get all the nice finishing touches that the 3 coupe has... like the orange ambient lighting along the doors and side trim at the back, as well as the rear passenger heating controls. I'll need to pop along to the dealers and have a proper look myself.
