Autotrader is fantastic. I think its like 75$, but your ad stays up there till the car is sold. Craigslist works, but be prepared for the "Dude I got 30k cash right now today". I found that if you're going to buy a car at the dealership you are trading your car into, they will give you a better trade-in value. For example, if your going to buy a GT500 and put the Raptor as payment toward one, they may give you $38k-40k. You'll get the most money selling it private party obviously, depends on how long you want to wait really.
