After setting up an ad with a couple of other (overpriced) sites, I decided to add Cars.com. I was very impressed with the price of FREE. When I finished adding the details and photos the ad looked great! It allowed easy edits (and there were many) and cost me nothing. Several prospective buyers were sent to me from cars.com--they were just as good as the buyers sent to me from Cargurus, ebay motors and Craigslist (Carvana was such a joke!). All of the features which concerned me (length of ad, number of photos, features listed, ad editing, ad price, popularity of the site, and site functionality) were available and of the same caliber as ANY of the paid sites. I'm not sure if there's a fee we have to pay if the vehicle sells (I canceled my ads after a couple weeks due to a change in business plans), but f there is it's a much better deal than the paid sites who charge up-front whether the vehicle sells or not. I will DEFINITELY recommend and continue to use Cars.com.
