This should help you....https://cargurus.uservoice.com/

Look at the top of this page and click on "Sell My Car" Fill out prompts and then in a day or so you will get a conformation email, you must prove, or I suppose just provide evidence - that the car is yours to sell. This is a reputable site, not craigslist - so the powers-that-be take a few steps to keep up their good standing. Your ad will not immediately appear, but only takes a day or two. But before you place the ad, take some digital pictures and save them in your computer. You will need them. For one thing, an ad with no images of car will be just ignored by shoppers
