I pulled profile images of 10 randomly selected Mid-engine, rear-drive vehicles that have been produced in relatively modern days. In chronological order:

2013 Alfa Romeo 4C

I'll also include the Ferrari and Corvette from the photo for more comparison:
2015 Ferrari 488
Italy
2020 Chevrolet Corvette
USA
So yeah. As you can see, they're all pretty much the same with slight variations to each one, regardless of what part of the world they came from. (Notice 5 of the above 12 were American). Different curves, length, height, width (which you can't see), overhang... but they all follow the same overall profile.
The 2020 Corvette looks like European supercars because since the 1963 Ferrari Dino and 1966 Lamborghini Muira, that's what they've done. The USA had muscle cars because we had straight roads, which pretty much don't exist in Europe. A mid-engine car handles better but has some serious oversteer if pushed hard. Americans never took to mid-engine cars because they are more difficult to drive. The Corvette has always been the Blue Collar supercar but has always been a little bit slower and less prestigious as its counterparts. Now it can finally compete at the same level or above while still being that Blue Collar supercar.
