The Aero is techniqually the fastest production car in the world... but its kinda like a pure race car... i don't believe it has things like A/C or airbags... the Veyron does... its more of a livable car to a degree... yes, both are highly priced... but i guess it i wanted just a beast of a car that went fast, i would get a Aero... if i wanted a car that went only 1 mph slower, but had more amenities and money was no object, i would get a veyor
