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
Good afternoon everyone, yes, I’m a lady and I’m an owner

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.
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 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!
I have enjoyed my vehicle.

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

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!

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!!!
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.

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!

I am really grateful for them they really turn my experience around and would come in the near future
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 team!
Great team! I Was a walk-in. Friendly helpful staff - went into look at a Canyon. I found the truck online. Salesman TJ helped with locating the truck and brought it up to the showroom. Even washed it prior to me seeing it ! Great financial staff. Quick and easy!! I Will return in the future for more vehicles.
Wonderful Vehicle.
I purchased to replace a 2017 Tahoe that I loved. Love this vehicle even more. Magnetic ride control, additional safety features the Tahoe did not have are great. Heated steering wheel a great feature. Heated AND cooled seats, will never be without again. Additional power of the Denali 6.2L vs. the 5.3L engine in the Tahoe is impressive. Bose sound system is outstanding.
