Best Car Buying Experience Ever
I had the best car buying experience ever! Jacob was amazing from the time I called and spoke to him on the phone and met him in person. He found the perfect car for me! The finance department got the loan done quickly and was very straightforward and kind. In conclusion, Everyone was friendly, had my best interest in mind, and was very professional. I literally was in and out. Easy peezy!
Great truck to own.
Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size truck.

I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Foundation Cadillac did it again—and honestly, I’m not
Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!

Worth the wait to finally have it
We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

Great experience!
Great experience! When I contacted Weld County Garage about a used vehicle, Sales Consultant Miguel Orozco provided exceptional service. Due to my 1.5-hour commute from the WCG location, Miguel provided photos and videos of the vehicle so I could be sure it was worth taking a full day off. I later learned that Miguel had come in on his day off to assist me, a gesture I genuinely appreciate. Having visited numerous dealers in my search, Weld County Garage stood out as the most helpful, professional, and customer-centric. They were not just interested in making a quick sale, but in understanding what I was looking for and finding the right vehicle that fit my needs and those of my family. Unlike many dealerships, WCG encouraged me to take the vehicle to my mechanic for a pre-sale diagnostic check, and all details listed on/about the vehicle were 100% correct. Like many, I have never had a pleasant experience purchasing a used car. However, thanks to Miguel and Craig, the entire process was painless and drama-free, instilling in me a newfound confidence in car buying -- especially with the right dealership staff. Thanks for a great experience, WCG!
Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Great Experience.
I am a college student and not always sure what to do when getting vehicle serviced. The people there explain to me what needs to be done and my options. I have experienced great service at this dealership. The experience here has been much better than I received at other dealerships.
Good afternoon everyone, yes, I’m a lady and I’m an owner
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

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%
2020 Yukon SLE. Highly recommend!
I previously wrote a review back in 2021 While I was leasing this vehicle. Which still shows up. I just wanted to give an update. I ended up purchasing it after the lease ended. So glad I did. I absolutely love this vehicle. Everything about it. Minus the high back end and price of gas but you're gonna get that with V8 engine. Have had since the spring of 2020. Haven't had any issues at all. Still would highly recommend. Comfort, look, safety, practical, A+ Best vehicle I have ever bought. I would normally have been in a new vehicle by now, I use to upgrade every couple years but not after this purchase, Still very 😊 happy

Great Service and a Pain Free Car-Buying Process
My wife and I were looking to replace a vehicle; online browsing led us to several choices from Drive N-Motion. My wife visited the location over lunch one day and met Zach. She left with a strong impression and Zach was quick to address our numerous emails. Throughout our search, Zach was personable and knowledgeable. We set the pace for our car-buying experience; Zach always made himself available but never pushed us to move forward. On numerous occasions, he adjusted his schedule to work with my wife and I. As we narrowed our search, Zach continued to provide us with additional options. Once we had sufficiently narrowed our criteria, Zach even searched Drive N-Motion’s incoming inventory and made available additional vehicles which fit our budget. Zach went above and beyond to serve us. He and Drive N-Motion took the car-buying process and made it as pain free as they were able.
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.
