You can go a few ways here. Carmax is a decent option. No bs, no hastle. In my experience with them they do offer a fair price. Your other option is to sell the car yourself. Autotrader.com is one way to go or Cars.com. With these options you make make a few thousand more and may be worth your time.

Ebay is there too, but in my experience unless you want near the wholesale price this is not the way to go.

If you are going to sell it to a private individual I would spend a few bucks making sure everything is fixed and perfect including the windshield chip and any door dings or scratches.
