We had a great experience here with Aidan. The whole crew is pretty low-pressure, which is refreshing in a car dealership. I'd highly recommend them to anyone!
Good afternoon everyone, yes, I’m a lady and I’m an owner
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 Honda dealership
Jeff Reed provided great service. He is attentive to what we want to know and goes the extra step to make sure he provides that. All the people we spoke to were professional and friendly.
Favorite car I have owned, to date!
The Yukon checked all of my needs, I have plenty of room for my children and my Great Danes. I enjoy driving the Yukon and how it handles, overall love this vehicle!

We did an emissons test, oil change, and wipers all
We did an emissons test, oil change, and wipers all around. Was driven to work, picked up and the vehicle was ready. It will reach 100,000 miles this month and it is like new. Everything as tight as when it was new, and I bought it new at Pundmann Ford some 5 years ago. Pundmann Ford helps me keep my car running like new.
Great family suv.
Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

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!!!

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.
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 had the absolute best experience at AutoNation in St.
I had the absolute best experience at AutoNation in St. Peters, MO. My salesperson, Anthony Smith, was upfront, knowledgeable, patient, and kind throughout the entire process. He never pushed me into anything—he made sure I was comfortable at every step and even gave me helpful tips on what to look for during a test drive. I later learned Anthony is somewhat of a local celebrity here in St. Louis, and it’s easy to see why. His approach and personality made the whole experience authentic and enjoyable. I also want to recognize Nate, the sales manager, who worked hard on my behalf to lock in the best deal for my situation. He truly went above and beyond to make sure everything lined up in my favor. And finally, Cameron in finance made the paperwork side of things stress-free. He explained warranties and add-ons so clearly that there was no need for pressure—the way he laid everything out spoke for itself. Because of his clarity, I was able to confidently choose what mattered most to me without feeling pushed. Altogether, this was hands-down the best car-buying experience I’ve ever had at a used car dealership. Anthony, Nate, and Cameron earned my trust, and I won’t hesitate to follow Anthony wherever he goes when I’m ready for another vehicle.

Great place to go if you're looking for a no hassle car buying experience. I came here because of the reviews and I left with the vehicle I wanted. Thank you for helping Scott
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

Awesome experience!
The whole experience was great. Super friendly. No haggling. Worked really hard to get us what we needed though. Vehicles were in excellent shape! Facility was very nice! Brandon our salesman was so friendly and helpful. We will be back!
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.

Honestly I am 65 years old bought 40 vehicles in my life it was one of the most pleasurable experiences I'm 65 but 40 vehicles in my life and this was a very straightforward enjoyment in my life to buy a vehicle from them I've ever had with buying a vehicle the people were great honest I don't believe they would rip anybody off and I would highly recommend they have nice vehicles all price ranges I go there first
The gmc Yukon from 2014 is very good it’s good for snow
The gmc Yukon from 2014 is very good it’s good for snow hauling trailers and children. What I love is the cozy luxury interior with the leather seats. It is very reliable the biggest problem we had was the cooling system failing but the repair cost was only $200. I kept everything on it stock. The sound system speakers are crazy good the base is 200% good I just love everything about it!

Mountaintop for life. Awesome experience
Found me a truck that I have been looking for. Had several on the lot but I’m very picky and knew what I wanted. Since they didn’t have the exact thing u was looking for, the salesman spent the rest of the day finding my truck. He went personally and picked it up and got it through service very fast and I was ready to roll with all tests ran and a great truck on top of it. Absolutely would go to this dealership again. Looking for a car and an SUV next year for the family. I will definitely be going back when I’m ready to pull the trigger on my/our next vehicles

I had a part go out on my car that was a recall. I was not able to get it into the shop but they came to me! They had the best service and made me feel like they cared that I chose them for my business.
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!

Everyone has been very conscientious and courteous
Everyone has been very conscientious and courteous checking back with me to determine what I want and if I was aware of the age of the vehicle. They also informed me that their service department wanted to work on some issues with the car and that they would let me know what they did and what work they believe still needs to be completed.
Big and Beautiful
I am a big fan of cupholders, this will make or break a deal for me. It could use more, but has a sufficient amount for the normal person. Beautiful body style and comfy.

We traveled over 4 hours to purchase our truck from Josh Cody and we would do it again in a heartbeat. The process was smooth and efficient. When you are picking a dealership for their great prices having a wonderful salesman is a great bonus.
I have owned my Acadia just under one year.
I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.
