I said 70 mph just to show that the Smart would have no problem on our highways. If you like speeding tickets, the Smart's maximum speed is electronically limited to 85 mph.
As regards to price, don't forget that Italians pay a 22% VAT (value added tax) on their automobiles.
The Smart may not be for you but there is definitely a market for it in North America.
