The 21st Century Tune-Up by Standard Motor Products, Inc. consists of a customer interview and a series of 18 "quick test" vehicle inspections, followed by diagnostic testing as needed. The customer interview gives technicians a sense of the vehicle's history, and the opportunity to find out how the customer feels about the vehicle's performance and how the vehicle is treated. The "quick test" vehicle inspections are designed to be completed in about 30 minutes, and will give an accurate report on the vehicle health, pointing to systems that need further diagnostic testing.
