With an average of 80,570 miles at 34 years old, FIAT UNO owners tend to use this car less than the typical driver. Very low mileage could mean the car has been garaged or used only for short trips, which can cause its own issues like battery drain and moisture buildup.

Buying a Used 1990 FIAT UNO
