I think they should add a Bugatti Veyron and Chiron, and maybe even other cars made by them. I don't think they should add them for the performance, but more for the looks, because I'm sure a lot of people would love to see it get added, and just buy it for its look (and of course give it a automatic spoiler that goes up)
I made a thread for the old beetle, would love to see it in game someday
