As I understand it, Lendaddy is spot on. You purchase "seperately" the body and the drivetrain and then it is put together in the US. This allows it to be qualified as a "kit car" so you can get around DOT regs.
Base price of $76,400.00 for a complete car.
I definately wouldn't mind adding one to my garage, it would look great parked right next to the Carrera.
