You need to check the used car's exterior and interior, take it for a test drive, perform a leak test, have a mechanic inspect it, check the right price, and review the vehicle history report.

If properly maintained, newer used vehicles can make it well past 100,000 miles before something expensive breaks. Some can even break the 200,000 mile mark. On average, though, used cars tend to be driven between 12,000 and 15,000 miles a year.
