We had an unfortunate experience with this dealership.

Reviewed by KM from Denver, CONovember 01, 2025

We had an unfortunate experience with this dealership. The interaction deteriorated quickly, with high emotions and unprofessional behavior. One salesperson even left a voicemail demanding that I “pick up the phone” despite us communicating effectively via text — there was no reason for that escalation. Additionally, he seemed frustrated that I have both a personal and work phone number, which felt unnecessary and unprofessional. The dealership also mentioned they had been scammed before and insinuated that I might be doing the same, which was both inappropriate and disappointing. To make matters worse, they failed to inform me that a rebate included in their pricing was set to expire at month-end. It’s the salesperson’s responsibility to clearly communicate rebate timelines and pricing details to customers. Overall, it was an unfortunate experience that reflected a lack of training and professionalism. I would recommend avoiding this dealership — there are other options in the area that value their customers and communicate more effectively.

?????????? 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!

Reviewed by Pam C from Littleton, COSeptember 08, 2025

Sales and finance teams were extremely flexible and attentive, listening to my concerns and working to find solutions. They supported 2 different test drives when I had a concern about a specific driving condition, being extremely flexible working around my schedule. Cam, Austin, and Alec worked together to provide answers to all of my questions regarding financing and extended warranties. When a last minute issue arose on a Friday afternoon, their maintenance department obtained the part and swapped it out on a Saturday morning to allow me to pickup the car that afternoon. Communication was excellent, receiving 2 status updates that morning.
