Used GMC cars for sale near Thornton, CO under $20,000

Initially I dealt with Dan, the owner, over the internet. Then I dealt with Steve at Castle Rock, then Martin at Parker. They were kind, caring, and helpful. Honestly, Dan may be the best communicator I've ever dealt with. He always responded immediately, I was mostly impressed with his immediate and accurate responses. I bought a 2017 F350 and I feel I got a great deal and was well taken care of. Thank you Berkenkotter Motors Tomm Olsen Michigan

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

Thank you Josh for coming to my house and replacing my windshield. On time and under and hour. Great work and much appreciated.

This truck is the base model and that is exactly what we were looking for. A good solid truck without all the fancy technology. It drives like a dream, handles just as well and the interior is sleek and well designed. Perfect black on black exterior.... a man's truck.

This truck is amazing, the design of the interior and exterior, the ride quality, the leg room( for a 6’3 1/2 person), it’s just absolutely outstanding. Would definitely recommend for a first truck

The salesman was very helpful and went out of the way to help me on this deal. I greatly appreciate his help. I would buy another vehicle from this location and not hesitate to recommend people their way. Again I thank Luis and the people at this location. Keep up the good work!

Great truck, solid engine, comfortable, smooth, and it handles great for such a large vehicle. Get one and enjoy miles of roadtrips with all you can tow or haul.

They were very helpful. I didn?t have to drive more than once, they were kind enough to mail papers. I felt valued as a customer.

Our 2021 Terrain SLT is really a nice auto. Gets great 30 MPG approximately, But, 0 to 60 is lacking horsepower. Great Little highway auto. Comfortable.....

Jillian was very responsive and worked hard to be fair and do her job well. Jillian is great! Our only annoyance was the long wait to pick up the car , which is minor in the scheme of things. Thank you Schomp & Jillian.

Just the right size for 2 adults, a child, two large dogs and two large ice chests to head to the boat with all our equipment and food. Hated to see them downsize it in '17. It has had few maintenance issues and they have been reasonable in cost. It has kept it's value over the years.

Sherry was easy to work with and made buying my truck hassle free. I would recommend this team to anyone.

I really like my GMC Canyon 2015 it's a very nice truck .it's been very good ,it does have a couple problems that I've taken care of but all in all I really enjoy driving on the highway in my truck.

Jon A was a gem to work with. He bent over backwards to find deal/price that suited me. He drove my car home that evening, so I didn’t have to find someone who could meet me at the lot later in the week. He researched and finally bought a charging cord for my new, leased EV (didn’t COME with a cord!! What’s up with that, Kia??). Couldn’t have been nicer and more helpful.

I love my 2018 GMC Acadia just wished windows were tinted and had a tv for kids and grandkids overall I have had this truck for 2 years and I Love it and use it for family drives cuz of how much room it has I have even used it for work meetings and we all travel to the meeting together .

​I recently purchased a vehicle from the Centennial location and had an excellent experience. The sales staff were fantastic and created a genuine, no pressure environment, which I greatly appreciated. I am absolutely loving my new car and would highly recommend this dealership to anyone.

Bought a demo car . The Acadia has been great . Wife’s car . She likes it . Roomy and good gas mileage . Would also make a great road trip vehicle if I didn’t have a full size Ram .

Was looking for a 2025 GMC Acadia Denali. Went to AutoNation and was met by Caden Noar. He was fantastic! Showed us the Acadia he had on the lot, gave us a test ride and answered all our questions. Not once, did he pressure us to buy but was more interested in answering our questions. After the test drive, we noticed a Buick Enclave Avenir in the lot as we were exiting the dealership. Liked the car looks and went back into the dealership to see if Caden was available to show us the car. We knew nothing about the car. He came out, gave us a test drive, answered our questions and then asked us if we would like to see another feature of the car, so out we went for another drive. Again, no pressure to buy and we parted. Over the weekend, we decided we really loved the car and called Caden on Monday to see if we could discuss the price and terms. Bottom line, we bought the car at the price we wanted. Outstanding service from Caden to the Sales Manager to the Contract/Finance Team!

I brought this truck in 2019. I kept taking it back to the dealership to get tweaked several times. Once it was figured out, never got any problems ever again. A little weak on the power side, but, other than that, its a magnificent vehicle. A total work horse. Great on gas. It is totally worth it.

Jalen was great to work with, overall a great experience from the time we walked in.

Extremely happy. Ride comfort, controls, comfort, looks, quietness, Quality. They should've kept the 2.0 turbo. But this engine not bad at all. Can't wait to get another.

Had a great experience with the service advisor, Eric on 8-27-25. Had a some questions for an app't the following day. Arrived at 5:00 and not only did Eric, the service advisor, save me a couple of hundred dollars, but was able to get the recommended service completed in a half hour without having an app't. I have not always had great experiences but this made up for the lack of attentiveness in the past. Have been a customer since 1990 and will continue to have Planet Honda in Golden to service my 2018 CRV Honda.

I had my 2020 Terrain for 5 years before I had any major issues out of it. My brake booster needed replaced. After about a month of it being out the shop someone hit and totaled it. Very sad day. I love my Terrain

Everyone at this dealership is a class act! Great service. Ask for Ed Rivas to be your lead salesman. He will treat you right and take care of your needs. Extremely knowledgeable and responsive!

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

excellent bought a good car good prices 100% recommended Fatima nuñez the best group 🙏🏻

Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

The dealership responded quickly and were knowledgeable about the vehicle I was interested in. They also maintained contact even though I didn’t purchase that particular car.

Test drive before you buy.....so far it's good but it's expensive for gas to fill up was $70. And city plates is $301 and also the car is heavier than the ford explorer that's why everything is so expensive

Great experience Diana helped me out a lot had an easy first time buyer experience drove of with what I wanted thank you Diana and Ethio Motors.

I just purchased a 2018 Acadia and I’ve been having oil pan issues. I took it back to open road in New Jersey where I purchased it for a high price repair and am still having issues

Nick was great. Very helpful and informative. Made a great deal on my trade. My second vehicle from Bozarth. Clean facilities.Thanks again. I will be back again.

Friendly staff, great price for the car. There was a far bit of waiting around but with the volume of cars they are shifting on a daily basis, it was kind of expected. From the very short test drive to driving out with my car was around 45 minutes.Would definitely use then again.

Sergio was very helpful! Good cars at good prices. Would definitely recommend buying a truck here.

I am 84 years of age therefore I have owned several automobiles and cannot compare any other that I have owned to this Acadia. It has been the best overall transportation I have ever owned!

Schomp Mazda was very responsive and attentive to my inquiries. The entire experience was gratifying.

Great vehicle, 65,000 miles and not a single issue, hoping to get atleast another 100k miles out of it. Extremely reliable. A family member of mine bought a Honda that broke down at 16,000 miles and got stranded. Would absolutely recommend a 2018+ terrain

We worked with Leon and Aaron(finance), got what we wanted. They were great! Highly recommend. Thank you!

I've owned my 2015 Acadia Denali since 74900 miles were on it and it drives great! I hear things on its quality but in my experience it's been a joy to own.
