Our promise to you

At Simon Auto Service LLC, most of the vehicles we work on have traveled many miles on some of the most remote backroads in Montana. Our goal is to help people care for and maintain vehicles that are getting older and have just rolled off the assembly line. We work on domestic American vehicles and specialize in 6.5 diesel and Duramax.

Auto diagnostics for all

At Simon Auto Service LLC, we aim to educate and share our knowledge with you rather than steer you toward the auto repair option that will make us the most money. To lifelong residents or visitors to the Flathead Valley, we promise to deal with you honestly, treat you with respect, and charge reasonable prices for auto diagnostics. Why go anywhere else for your auto diagnostic needs?

Driving in High Altitudes

The environment where you drive your vehicle can cause different malfunctions. Driving in Montana, you'll travel on highways ranging in elevation from 1,800' on the Kootenai River to the Beartooth Highway, soaring nearly 11,000' above sea level. These elevations can have a noticeable effect on how your vehicle runs. If you've just come from a mountain vacation, or been down by the seaside, bring it to Simon Auto Service LLC and get it right back where it needs to be for peak efficiency in the Flathead Valley.
