It depends. Does your vehicle have an intermittent drivability problem or electrical issue? Is the check engine light on? If so, do the stored faults require extensive diagnosis? Is the car in for routine maintenance that includes replacement of parts and fluids designed to be replaced? As diagnosis often requires the greatest amount of sophisticated equipment, technical expertise and shop resources, our diagnostic hourly charge is greater than our service and repair rate. While we utilize up-to-date industry and factory Suggested Repair Time data, it is important to understand that there is no direct relationship between the time spent on the job and its cost. Ultimately, you are paying for the results.
