2010 Jeep Wrangler four-door with 80,000 miles on it

I wouldn't be too worried about the number of miles on the Jeep. Mine has less than that now, but my Aunt's 2008 is still running strong with nearly 200k. Wrangler-4 doors hold their value incredibly well and finding them in the $20,000 price range is increasingly difficult. My suggestion would be to click the Car Values link at the top of the page (or follow link below) and plug in as much information as you can about the car. CarGurus will tell you how good the deal is based upon the information you provide. https://www.cargurus.com/Cars/instantMarketValue.action
