Outstanding customer service / warranty service / repair
Outstanding customer service / warranty service / repair service. Steve, Kevin, and the technicians came through again with a warranty repair in record time. I am very glad I bought an extended warranty to match my lease term, but it would be nothing without the service team here at AutoNation Jeep in Golden. A steering part failed on I25, and we experienced significant ?death wobble? (IYKYK). Steve responded to my text immediately and I went in two days later (my schedule). The whole repair was done in less than 3 hours, and I was on my way. The service department here continues to earn my loyalty each and every time I come in. They are fast, friendly, professional, and demonstrate a genuine concern for me and my Wrangler. Good customer service and good vehicle repair service are hard to find. Both are top tier at this location. Again, it is worth the half-hour drive from our house and more. Thank you from a very satisfied customer!
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!

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

Wonderful people
I recently bought a 01' Cherokee XJ in beautiful condition and could not be happier with my experience at One Stop Motors. Hassan is a true professional and made me feel comfortable the entire time I was on the lot. The staff gave me plenty of space to inspect the car and test drive on my own. Hassan was very efficient in processing my sale and made the entire transaction feel easy. I would recommend them to a friend.
Great truck with some bad
It is a great truck with great capabilities! although i must say, some of the technology in this car has its low points. Center stack tends to not cooperate during bluetooth pairing and the headlights have poor illumination to the point i had to retrofit LED bulbs for better visibility. Overall very comfortable ride and smooth drive

Great experience with Berkenkotter Rastle Rock.
We had an excellent experience working with Dan & Wade on the purchase of our new vehicle. The sales team helped us through the process and were incredibly patient. Used vehicle prices are out of control and it's comforting to know there are car dealers that go the extra mile. I would rate our buying experience 10/10. We will be back when looking for another vehicle. Give them an opportunity to earn your business!
Bad paint
They have very bad paint peeling problem, they also have a hesitation at take off , good ride ,good interior comfort , fair fuel mileage fair power, we have two in the family, I am very disappointed in the paint peeling issue,I have a 2005 2500 paint is good.

We felt heard, respected and valued at AutoNation Chevrolet North. And that?s saying a lot coming from this Ford loving family! James, Joe and Braden made the car shopping experience fun and the buying was smooth. We will check their inventory first next time we need to buy a car for sure!
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.

Awesome experience. The five star rating is too low, I'd give them a 15 star. No high pressure sales. Everyone was so nice and helpful, treated us like royalty. Roberto listened to what we wanted to look at, he went through the inventory, and we found the one we loved.

Fantastic dealership
My experience was great from the time I walked in the door, Luke, Mike, and Kelley were fantastic from showing me what they had in my price range to helping me get approved and out the door with a vehicle. Will recommend them to friends and family 100%
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.

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!

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.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

Service for my car
Helpful and kind, answered all my questions. Next time I'm shopping for a car, I will come to Luis. It's important for me to have someone I feel listens to what I need.
Exceptional truck with one annoying detail.
I truly enjoy every aspect of this vehicle except for the fact that to have my text messages displayed on the screen I have to use a cord and cord my phone into the vehicle. I can Bluetooth phone calls But I cannot get any messages to display without using a cord. For the truck being a 2019 and the price point of it that is absolutely absurd. Other radios that GMCsells has this feature. This truck does not.

2022 GMC Sierra SLT 3.0 Duramax
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!

It was worth the drive from Silverthorne to remedy a situation with a used Lexus GX460 that I acquired from WCG. The sales personnel were helpful, courteous, and professional and instilled confidence in me to return for future product and to refer anybody to go there for new or used vehicles and service. Ryan in sales and manager Derek got it done promptly which ended up being a faulty tire causing vibration at high speed. Also an honorable mention to Raul! Thank you all. I enjoyed the return drive to Silverthorne.
Overall I am very happy with my new Truck.
Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

Over-priced car.
Over-priced car. Sales person very persistent. Very far away from my residence. Not sure if I am interested or not. Have owned three other Mustangs already.
Pleased that I made this purchase
Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

After any serving of a vehicle taking it through your car
After any serving of a vehicle taking it through your car wash before returning to customer. This might encourage more customer loyality. Oil change prices are too expensive. The expertise needed to do that job doesn't equalate to charging that amount.
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.
