Great Experience
I did my research and found a great deal at Denver Auto on a Subaru Forester. The car was ready and waiting for my scheduled test drive. Right by the door. They let my mechanic look it over. It had just had lots of repairs/maintenance. My mechanic verified all this. Stan was great and I purchased the car!! Still going strong!! Thanks Denver Auto!!!
Reliable and feel very safe.
Love this vehicle. I feel safe transporting my grand daughters. It is reliable. It?s great on highway and city driving. I would recommend a GMC

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Fantastic experience!
Fantastic experience!!! I worked with Brandon and James, and both were terrific. Very knowledgeable, not pushy, and Brandon made sure I was able to drive every Bronco with all of the different options I wanted to compare. Dee made the paperwork easy and stress-free and overall I could not be happier with my buying experience.
One very awesome vehicle.

Great experience!
Bought a sierra 2023 for my business. The salesmens knowledge was excellent, process through finance was seemless and price was very fair! We appreciate a good dealership experience!
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.
Best truck I ever owned
Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else
