But for the most part, it is true...
By the time you spend the money to make a Euro model for the stateside market, including all changes for emissions, new crash tests with the new motor/ driveline ect. ect. ect.
Who is going to buy this vehicle with all of the above passed on to the consumer?
We all agree a 4 door family sedan that gets 60mpg, and comes with heated leather seats, corners like a lotus, and accelerates like a CTS-V would be awesome, but nobody wants to pay the 60-70K it would cost to bring such a machine stateside.
