I have been going here for years. Great shop with honest people. They get my car fixed in reasonable time frames, kept me updated throughout the process, and the quality of the work was excellent. Fair prices and great customer service. I’ll always come here first and would recommend them to anyone needing repairs.

Wilhelm Automotive Repair & Tires

This was my first time at Wilhelm. I went in thinking my thermostat needed to be replaced, but came away with only a relay for my AC fan. They listened carefully to what I wanted when I asked for a tire estimate and were very thorough. I will definitely use them again.
