TEST PROFILE A motor vehicle service is a series of maintenance procedures carried out at a set time interval or after the vehicle has traveled a certain distance. The service intervals are specified by the vehicle manufacturer in a service schedule and some modern cars display the due date for the next service electronically on the instrument panel. The completed services are usually recorded in a service book which is rubber stamped by the service centre upon completion of each service. A complete service history usually adds to the resale value of a vehicle.
