Honest diagnosis, fair pricing, no unnecessary upsells
Our story
JR Auto Care is a small shop built around one mechanic who does things the old fashioned way. Jason will walk you into the shop, show you the actual problem, and explain what it takes to fix it. No pressure to buy more than you need, no disparaging the last shop you visited, just a clear answer.
Customers come to us for everything from routine repairs to the jobs other places turn away, like sourcing and installing special LED bulbs a customer supplied himself, or confirming a dealer's diagnosis before paying dealer prices for a head gasket job. We move fast: most repairs get scheduled within a day or two, not left waiting on a callback.
A lot of our work comes from people who found us after a dealer's estimate did not sit right with them. We tell you what we see, price it fairly, and stand behind it. That is why customers keep coming back, some for over a decade.
What customers say
“Jason is an honest mechanic that will never try to upsell an unnecessary service. This is why I've trusted him with my vehicles for 10+ years!”
“Jason elevates customer service and auto repair to an entirely new level! He replaced six light bulbs at a more competitive rate than I found at five other places. What impressed me most was his ability to accommodate my special bulbs, no other shop was willing to install them.”
“Best friendly and honest service! Explained the issues and allowed us to go into the shop to see what the problem was. Highly recommend”
