Hi Scotty I know you say to never buy used car from a big corporation such as carmax or a car lot. Of these places can you list from the best place to buy used car to worst? Carmax, rental car agency, used car lot, and car dealership.
Buy used from a private individual selling car from elderly who's stopped driving, at estate sale, ask around-- in short: eliminate the Middle Man.
Always try to buy from a third party seller dealers overcharge
I would use none, you'll never get a true deal at any. They buy low and sell high, except for rentals, which were driven by hundreds of lunatics and maintained by minimum wage workers
