Odor. When you first open the car door, sniff the interior. A musty and moldy smell could indicate water leaks. Remove the floor mats and check for wet spots on the carpet. Pedals. The rubber on the brake, clutch, and gas pedals gives an indication of use. A car with low miles shouldn’t show much wear. Pedal rubber that’s worn through in spots indicates that the car has been driven a lot. Instruments and control. Turn the ignition switch, but without starting the engine. All the warning lights should illuminate for a few seconds and go off when you start the engine. Also try out every switch, button, and lever. With the engine running, turn on the heater full blast to see how quickly and how hot it gets. Switch on the air conditioning and make sure it blows cold as well. Seats. Try all the seat adjustments to make sure they work properly and that you can find a good driving position. Upholstery shouldn’t be ripped or badly worn, especially in a car with low mileage.
