The condition of the interior is perhaps the least important factor in choosing a car, but it is still important to know what it is that you are purchasing. Those wanting reliability over looks can be easily satisfied with a pair of seat covers over worn upholstery, floor mats over dirty carpet, or other cosmetic cover-ups. However, for the collector, condition of the interior can be important in its own right, if only to weigh the total amount of restoration needed.
Electrical Wiring
It is not uncommon for older cars to develop problems with wiring, switches, or relays. Be sure that all of the exterior and interior lights work properly. Also check other electrical components, such as the cigarette lighter and rear window defroster.
Climate Control
Although it may seem like mere creature comforts, it is still important to ensure that the climate control in a car is functional. With the car running at operating temperature, turn the heater on full and make sure that the vents blow hot air. Also make sure there are no signs of antifreeze leaking from beneath the dashboard; antifreeze in the interior indicates problems with the heater core and/or heater hoses, which can be a time-consuming and expensive repair to make. If the car has air conditioning, turn it on and ensure that the air becomes cool; it is also a good idea to stand outside the car while the air conditioner is on and listen for growling, grinding, or other abnormal noises.
Safety Features
For the safety of you and your passengers, it is important to make sure safety features such as seatbelts and air bags appear to be functioning properly. Federal and state laws protect owners of newer cars from defective safety features; if you have a concern, check with the car manufacturer’s local dealerships to find out if the car is eligible for free repair.
