The Honda S2000 remains the cheapest way to get into a street vehicle with the mean piston speed of an F1 car...unless you want to shove a bike engine into the side of a Toyota MR2, but those have been known to throw rods as often as Russell Crowe throws telephones at bellhops. Pick up your Australian throwing star and buy this 2005 Honda S2000 offered here on eBay
for $9,000 buy-it-now with a few hours to go, located in Riverside, CA.
