How often you should service your car really depends on your annual mileage and the manufacturer’s recommendation. Most cars should be booked in for a service once every 12 months, or every 9,000 to 12,000 miles. At PDH Cars, we recommend you follow the manufacturer’s guideline servicing schedule to get the most from your car, but we understand that every customer’s needs are different. However often you choose to bring your vehicle in for a check up, at PDH we make servicing your car as little hassle for you as possible, with 5-star service every step of the way.
