Gene’s Car Tips

Offer Every Service Our Customers Need

You don’t want to take your vehicle to four different mechanics. It is better to take your car to a single shop that offers every service that you need.

Certified Automotive Specialists is a one-stop auto shop. We provide oil changes, scheduled maintenance, emergency repairs, and performance upgrades. Our certified experts are trained to work on over 30 different makes of cars as well as trucks and SUVs. You can find a full list of our services on this page.

We only hire mechanics that are ASE certified. We also have five master technicians with various specialties. Our technicians inspect the vehicle thoroughly to ensure it meets our quality standards.

Commitment to Long-term Customer Satisfaction

Many mechanics believe that their job is finished as soon as they finish working on your vehicle. The experts at Certified Automotive Specialists are determined to help their customers long after they drive out of the shop.

  • We provide a two year warranty on all services and parts. Our technicians know that they need to do the job right the first time around.

  • We build close relationships with our customers to understand their needs.
  • We carefully inspect our customers’ vehicles during every visit. We notify them about any problems that may need attention.

Our commitment to customer satisfaction is the reason that our company has been consistently ranked the number one auto repair shop in the city.
