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!

No-hassle purchase
I purchased a 2001 Toyota 4-runner from Levi's this week - I found everyone there very friendly and helpful. They had no objection to my taking the car to my mechanic to be checked out - even though we were gone over an hour! when we got back, I was out the door with my SUV in less than an hour! After I bought my Toyota from them, I read some bad reviews that they had received - looks to me like someone didn't have the car checked out before purchase and had problems - that's the buyer's responsibility as all purchases are clearly "as is." I would NEVER buy a used car without getting it checked out first! Overall, I am very pleased with my purchase and with Levi's.
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

Outstanding purchase experience .
Outstanding purchase experience .. customer service was great . Car was prepped and ready as promised fir next day pickup . Dealership and all employees were awesome. Finance process was smooth and very quick ! Well done everyone
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.

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!

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.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

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!
A little expensive, but comfortable, quiet, smooth ride.
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Great customer service and I have owned 13 cars.
I bought my Escalade from them and they put the truck up in the air and let me look at everything. I found a small issue and they will fix it in my purchase contract. What sold me was the extended warranty they have a full service shop where they will handle my issues there on-site.
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.

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
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.

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!

Wife and I were in the market for a certain kind of vehicle, found exactly what we were looking for at this dealership. They contacted me right away and we ended up purchasing the automobile we needed. The important thing to mention is how extremely polite and professional everyone we dealt with seemed to be. Never once did we feel uncomfortable or pressured, they actually went out of their way to help us get this vehicle at a price we could afford. Our next vehicle will be purchased from this dealership and this wonderful staff!!

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?

Great dealership!
Great dealership! Great communication, easy to set up an appointment with, kind and knowledgeable staff. We worked with Tyler Donnellan and could not recommend him more! He was very transparent, kind, answered all of our questions thoughtfully and got us out of there within 2 hours. Andy was the finance manager we worked with and we also couldn’t recommend him more. He presented all the information clearly and made us feel comfortable. I would definitely come back when the opportunity arises. Thank you all! 🙏🏻🧿😊🚗
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.
