Hwy 123 Diesel & Auto Repair - San Marcos (TX)

5 /5 Josh: Travis at the hwy 123 Diesel & Auto Shop is an absolute legend! He is knowledgeable and explained everything clearly. The work was done perfectly, my 7.3 Excursion runs like a dream now, and the price was more than fair. You can tell Travis genuinely cares about his customers and his work. If you need anything at all done on your diesel, Traviss shop is the only place to go. Seriously, 5 stars isnt enough!

5 /5 Ol Son Outdoors: Travis and his staff are very professional and knowledgeable! They’re always considerate of people’s time and will work efficiently so you can get your vehicle back as soon as possible. Depending on budget they will send you quotes with a couple options for you to choose from. Great mechanic!

5 /5 Reddy Sarsam: Super service, Travis fixed our diesel truck at very reasonable cost. Even booked Lyft for me to get back home, started recommending this shop to all neighbors and friends. Very honest and intriguing mechanic, our diesel truck had unique issue and Travis spent his own time researching and studying the problem, took it as a challenge to fix the problem. Good Luck and God Bless you !

5 /5 Travis Roach: 123 Diesel will be the only place I take my truck. Travis knows his cars. Took my f250 in for him to do some maintenance. Very honest and fair pricing. He had my truck in and out the same day. Highly recommend Travis and Nicole for any repair needed.
