+1 Otherwise for me this car would be a very good 3 Series/M3 rival. It does not have any to do with that. They could add frameless windows without issue. The 1 Series 5 Door is normal, the 1 Series 3 Door has frameless windows, the same goes with the A1. I think Mercedes did not make the windows frameless, like the CLC (C Class Sportshatch), not too make it too close to the E Class. This may change with the next generations, CL will be, as it always was, a true S Coupé, E Coupé this time a true E Coupé and same for the C Coupé, a true C Coupé and not a late coming "cheap" build without finished design.
