What’s the least painful way to buy a car in Ontario right now? (FB Marketplace vs Dealerships)

Looking to get a car. Actually, strike that, I desperately need to buy something reliable just to survive my daily commute, but the whole market feels like a minefield right now. What’s even the best approach at the moment? Been scrolling through Fb Marketplace for weeks, and honestly, the amount of sketchy rebuilt titles and obvious curbstoners is driving me insane. My absolute hard budget is between $12k and $17k max. https://www.carhub.ca/
