    “Alex and his team have taken care of our diesels, Ford and Dodge, since he opened. When we moved away we still drove 1-2 hours to use this shop. Always great communication, solid work and pricing is lower than you would think given the quality. The only complaint is we recently moved to the east coast and can't use them anymore! Bring your diesels here everyone for everything!”

    “Dustin is awesome! Our rig is a retired school bus and sprung an oil leak while at Mesa Verde. I told Dustin the problem and he was able to track down a part and get us back on our journey the next day. He called a bunch of different places and cross checked things to make sure we got what we needed. Really thorough and knowledgeable. Thanks Dustin!”

    “This is an excellent mechanic shop. The team at Excel really knows what they are doing and provide excellent customer service. The multi-point inspect was very thorough. They fixed my original issue and provided photos of the condition of my truck, all fluids and any recommendations. Being a long way from home (TX) and towing a heavy trailer, the service they performed helped put me at ease and I felt like I received a very fair and honest service. Thank you everyone at Excel.”

    “When Ford in Longmont tried to charge me $4000 to fix a death wobble issue on my ford 2015 I went with Casey to get a second opinion as he has helped me before with excellent service. Casey and the team diagnosed the issue and it turns out my drivers tire was very unaligned and just required a alignment and balance. That seems to have fixed the issue and I cannot be more grateful with everyone at Twin Peaks diesel For diagnosing the problem correctly when the “professionals” at Longmont Ford didn’t even catch it and would’ve charged me for something totally unrelated. Thank you all so much and appreciate it always”

    “I arrived on the scheduled time. The front desk took my keys and said they would call me when it was finished. About a hour later they called. The oil change was done. But they found a concern with my front brakes. I saw the or what was left if my front brakes and ok’d the repair. Thank you PDA for your professionalism and care for my truck. If they hadn’t notice the problem with my brakes I could have had a accident.”

Very professional, great communication, and he gave me great advice regarding some other concerns I had on my Kenworth. Thank you very much to you and your mechanics for getting me out on the same day. Happy Holidays from Ferrer Logistics!”
