The Regera would be a very intressting experince be, comapared to any other car.
Considering it only has one gear, I guess car would be experinced familar to a Automatic. I still would love to see it coming thougth.
Also the Centenario would be nice to see, with its fullbody carbon fiber and yellow stripes.
The new bugatti is sweet too but since we have no bugatti brand yet it maybe less likely to happen? And if it happen the Bugatti should also have a circute spec, rember the GT Prototype thing that looked a bit like a LeMans prototype? that would be perfectly fitting as a race car enhachment for the stock car in my oppinion.
