Man, whatever you do, don’t drive over any speed bumps!
The overall shape and proportion isn’t bad but it’s completely spoiled by several things. The circular windows are silly and do not relate to any other element. Lose them. The visual excitement of any automobile is created primarily via the stance of the vehicle and the wheels. This has none, the fenderskirts are ridiculous, impractical and make the whole exercise look strained and self-conscious. The tail lamps are another dumb flight of fancy.
Strip those away and replace them with something in keeping with the supercar appearance as well as buyers’ expectations, and the exterior would work.
Once you get inside, that Impala dashboard is going to be more jarring and disappointing than the acres of cheap shiny plastic that greet you in a Corvette, though.
What, did he run out of money?
