🧠 Personal Tip
I’ve personally driven both a used Civic and a Corolla over 100,000 miles each. In both cases, they required little more than oil changes and new tires—and both still sold quickly when I was ready to upgrade. Buying a car with known reliability and fuel efficiency under $12k in this market is the smartest move if you’re looking at total cost of ownership.
