Who doesn't love eBay? I made a small fortune in college buying my text books for a semester and then selling them (always at a profit) on eBay at the end of the term. It has also helped me track down obscure parts for my stable of perpetual project cars. Besides books and car parts, I've sold cameras, computers, and much much more on eBay.
Never have I thought of using eBay to launch a company though. Ricky Søndergård, a Scandinavian, wants to find some capital investment for his new brand of lightweight, low-carbon sports cars. He claims his prototype makes 330 horsepower and gets around 80 mpg. Too good to be true?
