I used to work for the group that operates this service. They claimed that the prices were the lowest possible about 95% of the time. People would often say that they negotiated a lower price on their own, but this was more often due to them choosing a different vehicle or not following the process (never underestimate a car salesperson). I did not look over prices very much myself, but they could vary greatly between dealerships in different parts of the country.
