Ans: There are some basic differences. We're not going to go into too much detail and get too complex, but in general, dealers have ads on their websites and may advertise the car in a lot of places online. You can find one by searching for its name or the dealership's web address. Private sellers may try to sign up with dealerships and gain exposure that way, but they also place their ads elsewhere online. Nowadays, there is no such thing as just looking for a quality used car at your local neighborhood dealer because they are now so over-saturated with listings that you would have to work very hard to find one without paying a premium price.
