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?

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

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!

We had a very pleasant buying experience.
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 Dealership
Nice selection of trucks and vehicles with a very friendly and knowledgeable sales staff. Caleb and Rick were great. There was no pressure in the sales/buying process, all my questions were answered in a professional manner and there were no surprises when I signed the final paperwork. They are truly one of the best dealers I have ever dealt with.
I love it the look the interior mine is a red one and it

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.

I love my new Trax ….. Edgar was a great help in getting the deal done and I would recommend greens again just ask for him . It’s a real nice car rides smooth and Edgar will help navigate all the ins and out of the vehicle and answer any and all questions you may have .
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.

My recent purchase of a Chevy Traverse from Mills
My recent purchase of a Chevy Traverse from Mills Chevrolet of Davenport was a tale of two halves. Initially, the salesperson seemed to make getting the rates I wanted impossible, stifling any negotiation. But then, the sales manager stepped in and completely turned things around. He made sure we got the car we wanted at a great rate, making the rest of the process seamless. The manager's intervention truly made all the difference and earned my satisfaction.
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.

New car purchase experience
My daughter and I went to look at a new CRV. Aaron was a very knowledgeable salesman. He let us test drive a vehicle and it did not disappoint. All the features offered were what we were looking for in a SUV. We both liked the CRV, so we each bought a new car. The facilities are emmaculate and the staff is very friendly and helpful. A great example of the "team" environment. Kyle in finance made the process very smooth. We would definitely recommend the dealership to others. Consider Zimmerman Honda for your next vehicle purchase.

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

Best Service and Highest Integrity in the Business
After several years of helping me keep my 2013 Tahoe rolling smoothly down the highway; Jay, Randy and the Key Auto Mall Team helped me select my next ride -- a 2023 Yukon XLT AT4. Customer service is first and foremost with this team. I recommend all my friends and family to give them a call. I appreciate their hard work and will continue to bring my vehicle for service because that department rocks too!

The whole truck buying experience was made easy by Green
The whole truck buying experience was made easy by Green Family Chevrolet sales associate. He was patient and very professional, and made our experience a great one to remember. I would recommend Green Family Chevrolet to anyone who is looking to purchase a vehicle.
I love the truck. Dot trust that it won't brake do
The truck Handel's well. Sluggish when in second gear and the transmission thumps mostly when shifting down. Started about 40k. The ride is nice and comfy.

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!
