Ultimate Diesel & Auto Repair

My F350 had a fuel system error code and turned off on a major road. After getting it out of traffic I reached out to these guys where they were able to set up a tow and get the truck back to me running in two business days, parts having to be ordered and installed. Turns out the starter was faulty and shorting out the electrical system and fuel pump.

They also had great communication and called me right away with any updates they had. All in all it was a 10/10 experience, definitely would recommend !!

My son broke down while driving to a college rodeo in Texas (we live in Florida) The towing company recommended Ultimate Diesal. I went with it and I am sure glad I did. They kept me informed the whole time about repairs and timelines. They were reasonable with prices and Chis was amazing at explaining things to me. I HIGHLY recommend this repair shop.

It’s pretty difficult to find a competent and honest mechanic. Well, Frank, at Ultimate Diesel & Auto Repair is your guy. Frank did a post purchase inspection for me. He was very knowledgeable and honest about his inspection. He told me exactly what “needed” to be done and what repairs could be done at a later time. We set up an appointment, he came to the truck, and he did the work. He was courteous, professional, and a pleasure to do business with. If you need any work done on your diesel truck, Frank’s your guy! I can assure you; you won’t be disappointed.

I’d like to share a great business experience/review of Frank. My Vw Jetta gave out on me one day on the way home from work. The (EPC) light came out on my dash. I called the dealer for assistance and what I should do as a recommendation. Sad thing to say is the dealer didn’t care and wouldn’t help. I limped the car home and called various recommend road side mechanics. No one said they’d touch my car and was better off taking to dealer. Up until an associate of mine connected me with Frank. Frank came the following morning and told me I needed a Throttle body. I ordered the part and he installed it 2 days later. Frank was a life savor and really saved me the hassle of towing and paying the ridiculous fees. Highly recommend and wish you luck on your mobile business Frank ‼️
