A tiny one, but the M4 Competition rear badge should be black and not chrome. Btw, why does the G80 M3 have the sunroof and not the CF roof?
Because you can Order the M3 with both. Cabonroof without Sunroof and Stock with Sunroof
This game is about building the fastest car to take to the track. Sunroof adds weight at the top (steel, glass, and electric motors vs CF), so not only they gave the car more weight it isn’t an ideal place thus giving it worse center of gravity.
