Thanks Marcin Kenny & Jimmy
An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free. My salesman Marcin and manager Kenny went above and beyond for me to locate the perfect vehicle to fit my wants and needs along with staying in my budget. Jimmy also got me in and out with paperwork. Would definitely recommend all family and friends! Thanks Rizza GMC!
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Napleton Buick Service Department
Kept me informed of status of repair so I could decide if I wanted to wait for the repair. Customer waiting area always clean and comfortable. If the repair extends longer than I can wait, will provide.a ride home which is a great service. Always explains what is needed and what can wait until next service date so I can be prepared for future maintenance. This helps me keep my car in great shape and prevents major issues.
Awsome
Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Basically I was inquiring about a car and receive a quick reply. Unfortunately the car was missing a feature that was of interest to me so I did not pursue it but the saleswoman was nice and transparent with me and answered my question with honesty and accuracy.
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!

Kim was incredible in helping me get my repairs covered by my extended warranty! Details of service were provided and car was ready when needed.
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.

I spent a couple of weeks searching online for just the right Cadillac at just the right price and my patients paid off when I found Arnie Bauer Cadillac, and Rowland Laird. Rowland made the entire process, smooth and simple. He had the car detailed and inspected and ready for me when I arrive for the test drive, and was very helpful and professional the entire time. The finance department was very helpful and made it simple to work with my credit union to complete the purchase. I will be going back to this dealership again when I’m ready for my next vehicle in the future.

Great buying experience ever! Hands down!
My son and I visited the dealership looking to purchase his first car. From the greeting of the Sales Team to Finance, it was a great buying experience. A special thank you to Xavier Crump (Salesperson) and Dean (Finance), who made the deal happen. You don't find many people who actually care about you as a person and not looking just to make the "sale". My son is pleased with the purchase of his 2017 Malibu. We are appreciative of your dealership.

We are extremely happy with our 2024 Tesla. Louis was very helpful and kind. Thank you all so much!!
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.

The entire team at this location far exceeded our expectations! Our sales consultant Sandi was extremely easy to work with, and he had our best interest in mind when working on a deal for a new truck. When it came time to financing, Alex ensured we got in and out with exactly what we needed. He provided us personal stories bridging to his recommendations that help guide my wife and I in a direction that surpassed what we originally had in mind. Finally, throughout the visit Edgar and Manny ensured we felt comfortable as we worked though a deal that would ultimately have us driving home without any doubts in a vehicle that can grow with my family. They were the cherry on top to an already excellent experience. Thank you from the bottom of our hearts for such a great team!

Excellent as well as timely service. However, was not told in advance that paying with Credit Card would have a 3% fee.
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!

"THE" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

We worked with Brian Newcomb to purchase a new 2025 Buick enclave. From the moment we walked in the door, we felt at ease and were comfortable. Brian was down to earth, honest, and personable. He was knowledgeable and was able to answer all questions. We highly recommend Brian. He made the whole process headache free and easy!
Surprised myself and bought a GMC
I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.
