I buy new, end-of-year sales models. Drive them and sell them for a slight loss 2-3 years later to Car Max. For example, let's say the new car is $50,000. I wait until it's $42,000 or whatever, buy it, keep it for 2-3 years, and sell it for say $37,000. I've done that 4 times now. I don't understand the business model of Car Max, to be honest. There seems to be a lot of people who believe used cars are good deals, I guess.
