We had a fantastic experience at AutoNation Subaru
We had a fantastic experience at AutoNation Subaru Arapahoe. We were just starting our car search when we decided to stop at Subaru out of curiosity. Even though we had never owned a Subaru before, Bryan helped us figure out that the Forester was the perfect choice for us. We drove away with our 2025 Forester that day and haven't regretted it! We experienced excellent service by Bryan and Zachary (LoveSubaru).
new owner of the gmc denali, 2018 6.2

I was very satisfied with the service that I received
I was very satisfied with the service that I received from Auto Nation Chrysler Jeep on Arapahoe, and my service advisor Thomas Hatch. Mr. Hatch is very professional, and I enjoyed working with him.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

Nick was great.
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.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

⭐️⭐️⭐️⭐️⭐️ I just purchased a 2023 BMW X3M Competition
⭐️⭐️⭐️⭐️⭐️ I just purchased a 2023 BMW X3M Competition from Greenwood Automotive in Parker, CO, and I couldn’t be more impressed with the entire experience! I ordered the vehicle remotely, sight unseen, and had it shipped in an enclosed trailer to me — the process was absolutely flawless from start to finish. Stephen Case, my sales rep, did an outstanding job with excellent communication and professionalism every step of the way. What really stood out was how the team went above and beyond — the car originally only had one key, but they provided me with the second key free of charge (something they weren’t obligated to do) and even included all-weather mats for the vehicle at no additional cost. The whole staff worked together seamlessly: Steve Schwegmann, the business manager, was exceptionally helpful, and Brent McMillen, the sales manager, made sure everything came together smoothly to finalize the deal. I am very impressed, have zero complaints, and would absolutely buy from Greenwood Automotive again without hesitation. If you’re considering purchasing a vehicle — even remotely — I highly recommend Stephen Case and the entire team at Greenwood Automotive!
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

Beautiful Truck
I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Failed transmission and full replacement
We have owned our GMC Sierra 1500 for approximately 9 years now. The only real disappointment with the vehicle is that we had to have a full transmission replacement Just after the 100k mile without any warning whatsoever. The truck now has 107k miles on it and now , again out of nowhere, we are experiencing slipping in the trans and the engine light is now flashing. Very disappointing since we are starting to feel uncertain about the reliability of the vehicle now. The truck itself is gorgeous and shows ZERO signs of its age, sporting new rims and tires and a lifted body and no rust on the body at all. We hope there are no major issues with the engine as the vehicle has always been maintained as needed and on time for regular servicing at the dealership.

Our two Mazdas were total losses due to the Hailstorm
Our two Mazdas were total losses due to the Hailstorm that struck Cheyenne WY on August 1, 2025. I found AutoSearch USA through cars.com and contacted them about a Mazda CX-5 the had listed. Mike Blunn was great! They had just listed the car the previous Friday, and still needed top get some prep work done, but we set up a date to see it the following Tuesday. The car was not quite ready for us to take that day, so we made arrangements to meet at an Enterprise location midway between Cheyenne WY and AutoSeach USA's location so we could finalize the sale and turn in our rental. Everything went off without a hitch. I highly recommended AutoSearch USA for anyone looking for quality car buying experience.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.
