Most dependable truck i ever owned.
This truck is a beast, but with the Duramax diesel engine, its fuel efficient as well. my best average is 21 mpg which is insane for a truck this size.

Jerry was excellent from greeting to leaving after purchase!! He answered all my questions! When I wanted to compare vehicles side-by-side, he was most helpful in making that happen and making it easy for me to decide on the vehicle I was taking home that day!!
Loved the Duramax Diesel and an incredible truck
Incredible truck. Wanted to trade it in for a 2020 same truck but unfortunately the interior for this year hasn't been updated. Supposed to next year. Will check in then. Would never consider a Ford or Dodge over this powerhouse.

I worked with Tony from the service department and had a great experience! He helped diagnose an issue with the car I purchased from another lot and was very supportive the entire time. He called the other dealership to pass on the information, had his technician show me the issues in detail and even found me a larger rental vehicle to hold all of my kids. Wonderful experience working with Tony!

Start to Finish was fast and easy.
Start to Finish was fast and easy. Jace the salesman was fast and knowledgeable and answered every and all questions that I asked. I bought this for my 18 year old daughter and we drove 4 hours from home to buy from Dan Cummins. When we pull in her vehicle was by the door with a bow on it. Finance ended up saving me over 60 dollars a month on the payment. Awesome experience. Another plus is that they have multiple dealerships as far as Chevy, Ford, Ram. Will definitely buy from Jace and Dan Cummins again.

?????????? I had a great car-buying experience at Mike
?????????? I had a great car-buying experience at Mike Maroone GMC in Boulder. From start to finish, the team went above and beyond. A special thank you to Austin, the new car sales manager, Brayden, Cosmin, and Alec. Their customer service was outstanding, and what really stood out was their follow-through. Anytime I had multiple questions, they took the time to explain things in a way that I could clearly understand?never rushed, never brushed off. This wasn?t just about buying a vehicle?it was about feeling taken care of. The level of professionalism, patience, and genuine care made this the smoothest and most enjoyable car-buying experience I?ve ever had. I highly recommend Austin, Brayden, Alec and Cosmin, and the entire team at Mike Maroone GMC Boulder!
