He spent a great deal of time trying to locate the parts for us & finally found them 3 hours away, so we rented a car & went & picked up the parts. While we were gone, he got our truck ready for the new lines-- we returned at 3pm and he had it completed by 5pm!! Truly unbelievable customer service! And he had an extra car that he let us use & if it didn't have the "check engine" light on, he would have let us take it to go get the parts!! And finally, his prices were very fair! We can't say enough great things about Colby!

We were referred by a mobile RV service and it was a GREAT recommendation. Karson came over the next morning and replaced the starter. And replaced it again as the first one was defective. Even through that added aggravation Karson kept a smile on his face. We were up and running in a flash. We've been very fortunate to find great mechanics on the road this year ("new" old rig) and these folks continued our "lucky" streak! Thank you PDI!!! Karson, you're a great guy. Don't take this personally but I hope we never see you again! We all know that eventually we'll need some help on the road, and we are so appreciative that great folks like PDI are out there to help us. THANK YOU!!!

Southwest Diesel was the only shop to call me back, I left messages at 5 shops with good reviews to…read moresome maintenance done on my RV, they returned my call and put me on the schedule and were very helpful and accommodating with the other issues I had with my RV. They explained everything well so there wouldn't be any misunderstandings or surprises. The estimate was accurate and reasonable. They did all they could to accommodate my needs and then some. I keep saying "they" because I don't remember the guys name, I think it was Doug, When problems came up he updated and explained what and why but he had prepared us for the possibility that the manifold might be broken. I believe he was fair and honest which is a hard combo to find these days. If you need diesel work and in southern Utah call Southwest Diesel

After calling multiple diesel mechanics and all saying they could take a look at it in a few days I called Southwest Diesel. Darren said they were swamped but he'd take a look at it. As I was waiting in the office to give my information there was already a mechanic working on my rig. He came in and showed me the issue. I was going to need a new air filter and a new fuel filter and they both had to be ordered. I was thinking "great, how long is that going to take?" I kid you not, while the mechanic was removing my old air filter about 10 minutes go by and a pickup truck pulls into the lot and he says "there's your air filter". Maybe another 5 minutes go by and a different truck rolls in and he says there's your fuel filter. Amazing!! I went from thinking I was going to be stuck in St. George for multiple days to problem solved in about an hour. Absolutely top notch service. Super knowledgeable people. They talked me through the whole process and explained what each part did for my engine and what caused the issue. Can't thank and recommend them enough.

The nice man said, "come on down and I'll see if I can fit you in." Not only did he fit me in, he took my car in immediately, and fixed my problem. He did it with a smile and didn't fuss about the kind of car I have. I am not from St. George, but I come up often from Las Vegas. There were cars everywhere which show me how awesome this business is. I recommend going to CT Automotive and can say that I'll be happy to bring my car back if anything needs fixing. Especially if I'm going to be in town for a while. Thank you CJ Automotive for making my day smoother than it could have been.
