ZAP world is the importer of the gas smart, $20,000+ and 40mpg combined.

Once again, DC has missed the boat. If the smart had a blue tec diesel in it and was built state side and sold for the Canadian Base price of $16,500 and got between 60-80mpg, with a 70mpg combined, they wouldn't be stuggling to sell them here.
Watch out for the Japanese, their diesels are comming and they will continue to put a hurting on the German and American car builders.
