Earlier the auto repair shops could substitute parts like grilles, fenders and door panels from the manufacturers of the vehicle. The Original Equipment Manufacturers (OEMs) did not have to struggle for attaining the monopoly. But with the establishment of the autonomous manufacturers, the OEMs are facing harsh and strong competition.

The auto body parts manufactured by independent producers were not only less in costs but their very subsistence forced the auto companies to reduce their cost of auto body parts. The rates of the auto companies have been slashed by 30% or even more. This has proved a great deal in stabilizing the premiums for auto insurance.

The Certified Automobile Parts Association (CAPA) was formerly recognized in 1987 by the Auto Body Parts Association (ABPA) as it was curious to raise and perk up the quality of the auto body parts. CAPA also has the exclusive rights to disapprove the parts that do not act in accordance with their standards of quality. The auto body parts are checked randomly in order to ensure that the quality of the parts is being maintained. The certificate is approved only after the process of exacting the estimates of the vehicle and its parts.
