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!

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?

I purchased my vehicle from Keith Key and the process was very easy and he was professional. This is my second vehicle from Weber Chevrolet and ALL the staff are professional and friendly. They have a GREAT TEAM here and always will recommend this dealership. When I took delivery of my vehicle I noticed more people in the dealership and it speaks volume; people are trusting them. I would definitely purchase again here. Cuddles also to Anthony in the finance department and Brent the manager!!!

A special thanks to Brett Harness for following up with me and making my vehicle purchase happen even though I inquired about a different vehicle a month before. I was extremely pleased with everyone involved in the entire transaction at this dealership. Highly recommended!!
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

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

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.

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.

Purchased new in October 2024.
Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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.

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!

What an amazing experience I had dealing with Pappas
What an amazing experience I had dealing with Pappas Toyota, from the start to the finish. Dave Dubois was a outstanding! First he helped in answering every question on the new Hybrid Tacomas, even when information was slowly releasing upon first announcement. He then helped lead me through the process of securing a place in the waiting process. While waiting for the trucks release he quickly and attentively answered all my questions. Once one arrived he walked me through the process even staying after his shift. Dave is truly an employee who loves what he does and cares for his customers. Even going above and beyond his job description to seek out answers that didn’t relate to selling the vehicle. Brett Bales was another outstanding employee who explained and led me through the warranties and sales. He even went on my behalf to talk to other departments about after marked parts. These two truly made the experience a pleasure and one I will recommend to many in the years to come

Great Team!!
I had a great experiencing purchasing my car from BMW of West St. Louis. Dawn D. is an excellent person to work with. My purchase was remote and she acted as my eyes and ears, providing a trustworthy assessment of the vehicle I selected as if it were her own. She answered questions, made a video and was readily available to answer questions leading up to and through the purchasing process. The shipping process was seamless with a fast turnaround time. Armin H. was great on the purchasing side of the process. Extremely detailed and clear on cost, warranties, etc. All around great team to work with!
