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

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!

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.

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

Loved the personal attention! Christy Thorton knowledgeable and professional! She was able to help me figure out the best car within my budget and to fit my family's needs
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.

Above and Beyond Customer Service
This review is in full support of Clement Hyundai – a dealership located in Wentzville, MO – which has shown remarkable, above-and-beyond customer care. At the end of our leasing period for a 2020 Palisade, my wife and I purchased the car outright. The transaction was handled smoothly and thoroughly by salesman Jeremy Null. Following that, our car needed to go through a few inspections for the warranty coverage. In doing that, there was a faulty wiper installed -- requiring the car to go back in to get it fixed. While this could have been a very frustrating experience – as we live more than 30 miles from the dealership – the team at Clement Hyundai went above and beyond for us, recognizing the inconvenience. Especially Jeremy and General Sales Manager Patrick Piper. They picked our vehicle up and delivered a loaner, as well as provided other coupons etc. to make up for the situation. When my wife realized she left my daughter’s dance recital tickets in the glove box, they drove out to our home to deliver them to us. That’s the kind of operation they run: one that has the customer at the center of what they do. I’ve never experienced such superior customer service from any other local dealership – and I’ve owned BMWs, Audis, Toyotas, Hondas, Fords and other makes and models. Clement is a first class operation and should be super high on your consideration list for purchasing a vehicle or getting service.
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.

After intense negotiations we reached a deal that I feel was a descent deal of course I would have liked to have gotten more for my car and given less for theirs along with a few more concessions from them but overall I think things worked out pretty good.
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 recently purchased a car from this dealership, and I cannot say enough how wonderful the experience was! From the moment I walked in, I was greeted with a warm and friendly welcome that immediately put me at ease. Every step of the process was smooth, straightforward, and stress-free. The customer service here is nothing short of fantastic. The staff was knowledgeable, patient, and truly seemed to care about helping me find the right vehicle. Special thanks to the general manager, Scott, who went above and beyond to make sure everything went as smoothly as possible. He made what can often be a stressful experience feel easy and enjoyable. I would highly recommend this dealership to my family and friends because I know they would have a great experience, just like I did.

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

Went to look at a Rav 4.
Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.
