"I’ve finally found a mechanic I can trust to give excellent service as well as advice on what can and what should be done. Joseph worked on my Jeep as well as my RV making sure both were in good shape and ready to hit the road! He is truly a full service one stop shop. A great guy, easy to talk with and only does work that needs to get done. I highly recommend his shop!"

"Joseph senior is a good man. BUT the current operator, his son, left us stranded for weeks while our vehicle was at his shop, with multiple back and forths, our vehicle further damaged. Don’t be lured by the good reviews. This isn’t a trustworthy diesel repair shop, you’ll be ignored and ultimately very disappointed. Which pro improperly yanks out a battery after running it down causing the engine light toturn on because the ecm now thinks the vehicle has a manual transmission instead of an automatic one?! Endless nightmare."

"I thought I needed a new ignition switch while in Tucson on vacation, but Joseph came over right away and got me going on the spot. He is honest and affordable and we feel very lucky,"

"Great customer service. Joseph explain’s everything that they are working on and they have it itemized on my bill so I know exactly what I’m paying for. When I can I prefer to support local family businesses over big corporations."

"I’m so glad my husband and I found this place. We brought in our camper— a converted diesel ambulance— for some engine work and a tune-up and were extremely happy with these guys’ work and professionalism. They are the real deal, and they are honest and charge fair prices. They really go the extra mile to get you back on the road. I would recommend them to anyone within 200 miles. It’s hard to find a good mechanic you can trust, but with these guys, your vehicle will be in good hands."
