overall its very cool … reminds me of a cross between GTA3 and funkycops (saturday morning cartoon here in the states)
aside from the usual comments (tire peircing body, etc.) i would say to swap the way the two cars act.
corvettes for the most part are glued to the road. corvettes with independent rear ends tend to ‘squat’ before taking off. mustangs on the other hand tend to be the loose sliding ‘hot-rod’ with lots of horsepower (leaf spring rear ends do that kind of stuff). being in the 70s, the vette is worth far more then the stang as well… so the more expensive/fancy car would be the vette.
i would think being from (Edited : France) you may not be able to see these cars ‘street racing’ in real life, so this is more of a heads up on the cars and how they act, not a rip on you.
is that AdR’s mustang ?
i loved the intersection scene with the A-team and starsky & hutch 
your endo/wheelstand with the scooter at the end is also out of place… by about 15/20 years
