Original parts are generally used by franchised dealerships during a manufacturer’s service. If you book an appointment at an independent garage in Peterborough, they will most likely use aftermarket or OEM (Original Equipment Manufactured) parts during the service.
If you book a car service through BookMyGarage.com, you are unlikely to receive original parts, even if you book a SecretServiceTM at a franchised dealership. This is because you aren’t booking a manufacturer service.
