Nobody can say that this Toyota Prius is too quiet. An eBay user is selling a Harley Davidson-powered Prius used for racing. The opening line explains perfectly why it's going for so cheap: "Ebay says I'm supposed to 'Describe any defects, missing parts, scratches, or wear and tear also described in your item description.' Uh, there's a lot."
The engine inside the surprisingly street legal Prius is from a 1986 Harley Davidson Sportster 883 that's been bored 1100 cc and has 223,134 miles. If you buy the Prius you'll also get the engine donor, which now has a weedwacker motor and doesn't run. Check out a video of the "ToyoHog" below:
