A Family Affair Since 1980

Auto Maintenance and Repair Services in Thunder Bay

We are more than happy to help explain and inform our customers about the mechanics of their vehicles and help them understand what is wrong, what is required to repair and in the case of multiple repair issues, figure out the best approach before you get back on the road.

We will prioritize your repairs in order of importance if they can't be fixed all at once. That way, you'll be able to drive safely while avoiding a high one-time repair bill.

Free Estimates

No matter the needed repairs, we will always contact you and advise you of the costs associated with them. We will never service your vehicle before we get your authorization first and to do so, you must understand your car’s condition. If you feel there’s a problem with your car, we encourage you to contact us and book an appointment. Your family’s safety could depend on it!

Making sure your vehicle's steering and suspension components are working properly not only helps reduce premature tire wear but also increases fuel economy, improves control and handling as well as shortens stopping distance.
