I would go with craigslist, it has become very popular and a lot of people don't want the extra eBay hassle included in car buying (shipping, fees, no test drive, etc.) unless the car is rare. Just post on multiple craigslist cities within 100 miles of your location. It will get you more exposure and most people are willing to drive a few hours if there interested. If worst comes to worst you could try carmax.
Hope this helps!
