Repairing a vehicle can be costly. That is why it is extremely important to follow the manufacturer’s service interval recommendations. If your car is in need of a repair be cautious when shopping around, the lowest price may not be your best choice. Most facilities charge labor rates in two ways: flat rate (also known as book time) or actual time. Flat rate uses a manual to look up the time it should take to complete that repair. If it takes more or less time than the flat rate, you are still charged the same. Facilities that charge actual time bill out the actual time that it takes to repair your vehicle. Some services may have an advertised set cost (e.g., oil change for $29.95).
