A classic car with replaced parts is worth less to collectors.
A well-preserved or properly restored antique car may be interesting to look at and fun to drive, but if you're interested in the monetary value of a classic car, you should know match numbers. Matching numbers means that a car's parts, most notably the body and engine, have matching serial numbers. If an engine has been replaced, or even if the car's paint color has been changed from the original, it will be less valuable to collectors.
Instructions
1. Read and write down the VIN number located on the dashboard of the driver's side.
2. Check the abbreviated VIN numbers on your engine, transmission and firewall, located behind the blower motor.
3. Compare these numbers to the long VIN number from your dashboard. If the last six digits match, the car is considered to have matching numbers.
4. Check the data plate under the hood or on the door jamb to find the color and trim codes for your vehicle.
5. Look up these codes in an ID number catalog to determine the original color and upholstery of your car. If you plan to restore your car, it will be more valuable if the color and upholstery match those of the original model.
