Looking for that post-Christmas car bargain? This is why we\'re here.The day after Christmas is known in the U.S. as the best day of the year for bargain shopping. Now this made us wonder: What is the cheapest car now being sold on eBay? After roughly a minute of searching, we had our answer.This 1951 Chevrolet pickup is now up for sale with a \'Buy it Now\' price of $500. However, it only has a $100 reserve. Judging fairly accurately by its appearance, we were correct in guessing it hasn\'t been driven in decades, since 1968 to be exact.It has been parked in its current location ever since. The owner claims it belonged to his grandfather and that the six-cylinder engine and transmission are still intact.Besides that, the bed is in bad shape because it was made out of wood and has since been eaten away. So is it worth $500? For the eventual buyer, be sure to bring a flatbed when hauling it away.
