    Jason worked on two of my diesels years ago when he worked as a diesel technician at Ford. It was always done right the first time and I never had any problems with his work. I don't own a diesel at the moment but when I get my next one I will be taking it to him for service.

    Being out of town I needed to find a reliable diesel performance shop to take a look at my truck. Unfortunately the Yelp reviews led me astray because this shop is far from professional. I dropped my truck off because it was making a incredibly awful noise from the turbos and I explained this to them. The next day comes with no phone call so I give them a ring and am told that their techs are driving it around. He promised to call me at the end of the day which he did not and when I called he just further explained how they have been driving it around. Well as any good shop would do they would pop the hood and start looking around. He told me the next day he could hook my turbos up and run a test which I would have been more than happy with. Next day rolls around and its 2 of clock with no phone call. I call to check in only to get a response that his tech is out driving my truck again trying to recreate the noise I had. At this point I told him to bring my truck back and I was going to pick it up. After a short conversation with the guy up front about how he can't do a diagnose it until he hears tHe sound so I leave and get in my truck to discover that it is cold and that really no one was out driving it. Moral of the story is this shop is far from professional. Any good diesel mechanic could of popped my hood and seen I had a turbo seal leaking oil possibly being the cause of the problem, but they didn't. Anyone who knows diesels and is into diesel performance STAY AWAY FROM THESE GUYS. I mean what to expect from a guy who used to be a ford tech? What a joke. Below are pictures of turbo issues I had that these guys failed to even notice probably because they didn't even open the hood. Edit: Took my truck my much more reliable shop, took it in same day, found my turbos seals were bad and bad crossover tube seals and replaced them same day I dropped the truck off, that's a reliable shop! Also, I didn't try to pass my truck without emissions. That was the first thing I mentioned to your employees because I know how it may affect your shop with the EPA. As an owner you should be more aware of goes on in your shop.

    These guys are super honest, straightforward, and good at what they do. I recommend them to anybody that has issues with their diesel.

About a year ago I got quoted $1,400 by Midas to get my axel boots replaced on my Toyota yaris. I called him in desperation-- my parents had brought their cars to him before but I had never brought mine in, but I had heard great things. I left a message and a couple days later he called back and said I could bring in my car early in the morning so he could take a look, no appointment needed despite his crazy busy schedule. He let me know that the issue was not nearly as bad as I had been told and that he could do the job for half of what Midas had quoted me. This was my first experience with him and he has consistently shown how much he truly cares about doing right by people and taking care of their cars honestly and to the best of his ability. I feel like I could trust him with my life. When he retires eventually I will have to go into mourning. If you are not sure whether the wait for an appointment is worth it, ask yourself if you can afford to pay double whatever he will charge you to another mechanic who will not be nearly as thorough as he will be. Recently, when he had to refer me to another shop because I needed a service he doesn't provide, he asked me to still follow up and let him know how it went after the work was done, just out of the pure kindness of his heart. He is a one in a hundred million kind of mechanic.

They charged $280 just to diagnose it, and even then, they weren't able to actually fix the problem because they said they couldn't find the part. For a car as basic and common as a Ford Focus, that didn't sit right with me. What was more disappointing was the overall experience. The communication wasn't helpful, and the attitude felt dismissive rather than solution-oriented. If you're going to charge that much for diagnosis, I would expect clearer answers or at least some guidance on next steps. It also felt like their focus has shifted since moving locations. There seemed to be a lot of attention on vintage and specialty vehicles, and less interest in helping someone with a standard daily driver. At this point, I'm getting a second opinion because I don't feel confident in the diagnosis or the value of the service provided.
