Took my car for some noise. The folks there effectively found the root cause and helped fix it. They even recommended the cheapest alternative versus the expensive one which other car mechanics would quote.

I brought my car in for brake pads replacements and a tune up. Ryan was very respectful and fair with how he priced my services. They were quick and responsive. 10/10 would recommend. Love this place.

"Not your Huckleberry" who says something like this to a customer? I had my own parts, just needed a radiator installed. No need to be rude. Won't service with you.

Backed into a fence and smashed my tail light. Car Tek was able to order the new light and have it fixed the same day as my call. They gave me a good fair price, and were able to patiently explain why everything needed to be done. They were very kind and patient with my questions and various fixes.
