So Iím eyeing a used 2019 S60 R-Design T6. The Carfax is clean but says it was a rental. Hereís the kicker, it has less than 800 miles. It was bought as a rental, driven for 700 miles over 7 months, then sold at auction. What should I be wary of? Iím not in need of a new (used) car, but Iím intrigued.
