WTF?
Why would they keep it from the US? a car like that has a crazy big engine, which means crazy bad fuel mileage, and there wont exactly be a big line waiting for it's showroom arrival. I'm sure someone in Europe will buy one, but even the Uber-rich people will resist buying one just because of the huge fuel costs.
so in the US, there might be more demand (or, perhaps, requests) to export it here.
