Adair & Sons Automotive and Diesel No matter what the problem is, our technicians always provide exceptional automotive services.

In 2022, Adair & Sons Automotive purchased Marioshop, which has served Round Rock, TX since 2011. Adair & Sons carried forth the general approach to automotive repair that had been followed for many years. However, Adair & Sons augmented the services provided to the community by adding TEXAS state inspections, as well as the servicing and repair of diesels. Adair & Sons Automotive service list includes auto and diesel diagnostics, car/truck engine and AC repair, suspension replacement, cooling system repairs, fuel system repairs, and so much more. At Adair & Sons, we provide practical solutions to solve your auto repair problems.

At Adair & Sons, customer satisfaction is the number one priority. Our reliable team of pro mechanics are licensed and insured to provide you with top notch repair services on both foreign and domestic vehicles.

Showroom Update:

Hi y'all! Just sharing a recent event that we all thought was quite cool. A long-time customer came in for maintenance and brought us a very old license plate to add to our collection! This customer lives in Round Rock, not far from the shop. Their property has some acreage and an old building on that lot. This license plate had been lodged in the ground inside that building for decades. The customer found it and donated it to the shop. WAY COOL! We decided to hang it on the wall just underneath the "RENTME" license plate that another customer gave us years ago (which is also WAY COOL!).

From all of us in the shop, thank you so much for your kind donation. We appreciate it! đź‘Ť
