> buys your car for much less than it's worth Which is clear, if they buy it from you, then sell it to a dealer who then sells it to the next owner. These are two intermediate steps where someone needs to make their cut. You as the seller would get the most if you sold directly to the next owner, but that is much more hassle for yourself. You have to make appointments with people who want to see the car, test drive it, ask a lot of questions, and then try to bargain for a low-low price. If you sell to one of their sites, you get less money but it's a very simple and quick transaction.
