No service writers. No layers of management to get in the way. If you have a question about your car or our service, just grab anybody and ask. We believe that being the biggest isn't necessarily being the best. In order to stay in business this long, at the same location, we must provide what our clients want. We offer straight-forward, honest service. We diagnose your problems and discuss with you the best ways to repair them. We understand that it's your car, not ours and involve you in the process.


We have taken major steps to stay up with today's automotive technology. We have the equipment required to tackle the most difficult problem.


Cars are changing fast. We seek out the best training available. We are graduates of, and big supporters of, Carquest Technical Institute. Jim has participated in every "hands on" class that CTI has offered and has acted as an assistant instructor in the second running of each of these classes. Still, there are things that we aren't comfortable repairing, and we will tell you this up front before our education costs you. We have the certifications to assure you that we are on top of our game.


We also understand that the clear majority of automotive problems are simple in nature and don't try to turn them into expensive nightmares for you or us. Preventative maintenance is also a good way for the consumer to keep their cars operating the way they were designed. It also has been a way of taking advantage of consumers in our industry. We try to prioritize these items for you, so you can see the potential benefits to you, without wasting money on needless maintenance. Bring in your owner's maintenance manual and let's talk about it.

Added Value

We keep computerized records on your vehicle. When was your last service done? Ask us! If we serviced it, we will have a record of it.

Planning a trip? We can check your service records and suggest any items that may insure your trip is trouble free. We have found that with today's hectic schedules, it's easy to forget when services were performed, which can lead to more expensive repairs in the long run.

Our long-term customers give us an edge. We then have complete records on their vehicles and can make more educated suggestions on what may or may not be required for trouble-free driving. We understand that your long-term business is much more valuable than turning a quick profit. Our commitment to you is to do whatever possible to service your needs to your satisfaction.

Our records also make warranty repairs easy to verify. We treat warranty repairs as a priority, and offer a National Warranty, Roadside Assistance and Road Hazard Tire Protection. As a proud member of the TechNet professional network, these warranties are honored at over 12,000 repair facilities across North America.

We now have, as part of our website, a "My Garage" page where you can peruse your service records, recommended service intervals, recalls, etc. You just need to set up the login information and with a couple days you will be able to see your service records beginning in 2013. Questions just stop in and ask for help.

Please give us a try today!
