"They know what they are doing when it comes to Cummins engine. Diagnosis can be very difficult, they will figure it out."

"I would like to thank the whole team at Marini! You guys picked up the pieces that MHC left me in. I found out shortly after buying my truck from MHC Denver that it had a leaking fuel injector cup. I had coolant that was leaking into the fuel system. I only put around 100 miles on the truck when this issue came up so I brought the truck back to MHC to see if there was any help I could get from them, but what I received was a very shady and negative attitude. Immediately they were acting defensive and irritated. I was the one who should’ve been upset. I felt like I had to beg them just to get nothing out of them in the end except for a bad attitude and a sorry about your luck. I ultimately decided to take my truck out of MHC Denver and over to Marini Diesel. Best decision ever! I can’t say enough about these people. I never felt uncomfortable at Marini. They were honest with me from the beginning to the end. They never played head games or tried to up sell me. They worked effortlessly to get my warranty to cover the cost which they eventually got them to do! MHC could not. They were also fast and responsive. What more could I ask for? I will definitely be back for future repairs. I will also be referring Marini to all my truckin buddies. Shout out to Korry and Jeremy, I look up to those guys like true friends. Thanks -Pat"

"I own a small fleet of trucks. At this point, I only trust the boys at Marini to work on them. Every time I bring a truck in, they are upfront and clear about the costs, and what they want to do. I appreciate the way they do business, and it’s a plus they are locally owned. Easy to support a small business when they are the best option."
