The Globe and Mail Published January 12, 2021 AdrianHancu/iStockPhoto / Getty Images The short answer to the question “Which used car should I buy?” is that there’s no short answer. There are hundreds of thousands of used cars for sale right now in this country, and they run the gamut from good to bad to very, very ugly. The only way to figure out which one to buy is to do some homework. The good news is that you don’t have to be a car person to figure out the answer. It’s not difficult, but it takes time. Sorry, there are no shortcuts, short of lucking into a hand-me-down from your relatives.
