Step up, R. E. Humbertson (or his heir; Mr. Humbertson would be 85 if he's still around)- Tulsa has a Belvedere with zero miles for you! Sure, there's a bit of water damage, but we bet the eBay value of the intact parts (there should be something intact) must be worth having. The deal back in '57 was that whoever could predict the population of Tulsa 50 years in the future would win the car. Humbertson's guess of 384,743 was the closest to the actual 2007 population of 382,457, so the Belvedere is his.
