We understand that reliable auto repair is very important to you, so here are the questions we recommend you ask. We are confident that you’ll find our answers to be satisfactory.

Yes, they are! Ask about our parts and service warranties when you schedule your service.

We have over 35 years of experience in auto repair and service.

We have an average rating of 4.5 out of 5 stars based on over 300 reviews! We’re quite proud of that, and we invite you to read for yourself how satisfied our customers are.

That’s a very important question, and the answer is that it varies depending on your vehicle’s condition and the repairs and services needed. We do everything we can to perform all repairs and services in a timely manner and will keep you informed along the way.

Of course! We will make sure you have all the information you need before we repair your car or truck. There will be no surprise fees.

Tires typically have a lifespan of around six years or between 36,000-75,000 miles, but this can vary depending on factors such as climate, maintenance, and driving habits. It’s important to remember that regardless of their appearance, tires should never be used for longer than ten years.

Before proceeding, it is advisable to check the recommended tire measurements by referring to the owner’s manual or the placard placed on the driver’s side door jamb. The label will contain crucial details like P215/60R16 94T, where the first part, P215/60R16, denotes the tire’s size measurements, such as width and diameter.

We recommend you follow your manufacturer’s recommended service schedule, and you can read our guide, Factory Recommended Service Intervals For Most Vehicles, here.

Checking your vehicle’s owner’s manual for your specific vehicle’s recommended oil change time is always a great place to start. However, most vehicles require you to change your oil every three months or 3,000 to 5,000 miles, depending on your oil type.

If you are unsure of when your vehicle’s last oil change was, we can help! Stop by to have your oil checked and changed if necessary!
