Had a great experience at the Muffin Shop in Spicewood! I was traveling through the area when I suddenly got a flat tire! I pulled off the road and as luck would have it, it was right in front of the shop!
Daniel Q.
The Muffin Shop is outstanding! They performed the state-required inspection on our RV. Their customer service is do good, we brought the RV back for an oil change. We enjoy supporting locally owned and operated businesses like the Muffin Shop. We'll be back!
Kelly T.
Amazing peace of mind, unmatched kindness and they wouldn’t allow him to even give them a tip as a thank you for their time and inconvenience. We will definitely be going back for all our auto service needs. Amazing to have such great folks nearby. Highly recommend reaching out for all auto service needs.

Bolt fell out of the shifter linkage on my motorcycle while I was on the road. I was left pretty much stranded slowly cruising down the shoulder unable to shift. Pulled into the Muffin shop in Spicewood. They happened to have the bolt size I needed. Got me back on the road. Thanks again!!!
Halle N.

Jonathon D.
Great service by the owners. Nice people. The owners were real down to earth people and doing the work. Even chatted a little bit how they own the oldest shop in Austin. They don't just run the place they do the work!

Great experience all the way around. Team was able to repair a crack in my muffler in less than an hour for a very reasonable price. Car sounds and runs great again. Will be back for future services! Thanks to the entire team at Muffin Shop!

Lindsey and her team were very friendly!
Did a last minute oil change and they even threw in a key fob battery when I mentioned needing one. Great service and I’ll definitely be back.

Figured out a tricky issue with my work van. Communicated well, and got it fixed.
Expert Check Engine Light Diagnosis You Can Trust
When your check engine light turns on, it’s your vehicle’s way of telling you something isn’t working properly. It could be something minor or a more serious issue, but without proper diagnostics, there’s no way to know for sure.
At Muffin Shop Auto Care, we use advanced diagnostic tools to read and interpret the codes behind your check engine light. Our goal isn’t just to identify the code, but to understand the root cause of the issue so it can be addressed correctly. Ignoring the warning or guessing at the problem can lead to bigger and more expensive repairs. That’s why getting an accurate diagnosis early is the most important first step.
