The company works on all makes and models and handles everything from oil changes and tune-ups to transmission work and front-end alignments. It’s also qualified to work on fuel injection systems and vehicles with advanced electrical systems.

Automotive industry veteran and ASE-certified mechanic Peter Kwong established United Performance Corp. in 1989. Over the past two decades, Mr. Kwong says he’s earned a reputation for honesty, quality and friendly service. “We like to offer a warm, friendly atmosphere. Our customers are like family, and we always enjoy adding new members.”

United Performance Corp.’s technicians attend regular industry seminars to stay updated on trends, technology and general information. Mr. Kwong also stresses the importance of communication between his employees and his customers. “From the beginning to the end of a repair, we’ll explain exactly what the car needs and why. If it needs more work than what was quoted in the estimate, we won’t move forward without approval.”

Company Philosophy

“Our business is taking care of cars, but it’s equally important to take care of people. We strive to be honest, offer good value, give very personal service and make the repair process as convenient as possible. We want to make each customer’s experience a positive one so they come back and enthusiastically recommend us to their friends.”
