OH!.....a sports car.
Now just hold on a second.
You said:
The Bugatti Chiron is THE most perfect car ever designed.
I'm pretty sure some of those Ferrari, Porsche, Audi and Saleen factory Gran Prix entrys are also no slouch as a sports car.
That's probably main reason the Bugatti even exists.
You forgot the supercar "Pagani" from Italy that offers even higher performance than the others you mentioned. When I visited a new Italian partner, he arranged a private, after hours tour of Pagani which led to my being interviewed by the "Robb Report".
Of course Ferrari designs some true, high performance autos...but doesn't come close to Bugatti Chiron in engineering, performance, styling & luxury.
btw, here's the Pagani "Huayra" Roadster...
