I put a car on eBay, and will never do that again, I offered a car that was fair priced and it was a nice car. All I got was insulting questions, and even more insulting offers. (I mean 25K less). It was only a 60K car, and I was offered 35, and 40K. I ended up selling the car by word of mouth.
I think the best place would be here, I like to think that people on here actually "Like" these cars and know its not about the money. If your all about the highest cash offer then maybe playing the ebay or facebook games is best for you. (Look at that facebook 67 Shelby, a posted price, turned into highest offers).
Lets face it, the market is down, people are getting older that love these cars, and the new generation does not want to own anything anymore. If anything, they want new ones that smoke the older ones., Its hard even to fine someone who will work on them anymore.
