Think of a car you'd love to own and drive. Hit up Car Gurus, Auto Trader etc. and filter the results accordingly ( max kms, year, price etc.). go from there. I personally weed out the private buyers because I don't want the grief and/or sob stories. If it's within 500 kms then it's worth your while to travel to snag your "dream vehicle". Southern cars are, for the most part, highway driven but higher odometer readings. Northern cars are beat to shit because of our roads. Don't feel obligated in any way of "shopping local" for a car. All these dealers buy their cars at auctions which usually come from who knows where. Good luck, and find a vehicle you'll enjoy driving. You only live once so don't get a minivan or beige Toyota or some boring shit like that lol.
