I'd definitely try Craigslist first. I'm not sure a Camry with a blown headgasket is the kind of car anyone would be willing to fly cross-country to buy, so a vast majority of folks who look at the listing will probably write it off as too far away. I typically look at eBay to find local "beaters" on the cheap, and have NOT had good luck selling project cars on eBay. Craigslist is regional, and free.
