Don't mind NCC, he's just bitter that you're getting the 10Gs and didn't offer us 10% for helping you.
If you live in Palmdale, 10Gs isn't that much ... that's like, lunch there, isn't it? NCC and I are from an area where that's a half year's salary, so be careful how you toss around dollar signs.
As to the roadster, if you can repair it yourself, source the parts and know a lot about everything, go for it and see if you can import it. But if you're 15 and all you've got is cash... get something widely distributed. The Smart may or may not be for you... you'd be dependent on a dealer network for a car that sells 25,000 per year vs. something like 500,000 per year for some individual GM models. That said, the Smart fortwo isn't a Toyota, Hyundai or anything commonplace - it has a personality, and you either love it or hate it.
