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!

I had a great experience working with Jason Archimede
I had a great experience working with Jason Archimede from start to finish. I wanted to upgrade from a sedan to a 3rd row SUV and he took the time to ask questions and listen to what was important to me in a vehicle. I did not have a specific vehicle in mind when I began my search so I appreciate all his time, effort, and flexibility to help me find what was right for me. He is very knowledgeable and I absolutely recommend working with Jason. I have nothing but great things to say about Jason and the staff at Boucher Nissan I met among the way. Thanks Jason!
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.

el mejor lugar para comprar autos y crear tu credi
Excelente dealer para adquirir un automóvil, muy buen trato, y sobre todo disponibilidad para brindarnos un buen servicio Y los autos en muy buen estado además que que te ayudan mucho para poder construir tu crédito
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.

We purchased a used car from Robert and he was extremely respectful and went out of his way to be helpful. We needed to get a car trailer to get the car back to Louisville Kentucky. He was able to find one and reserve it for us. Everyone at the dealership was very nice and helpful. We enjoyed dealing with everyone. We will always remember the great service and friendly staff. We will remember them if we make any future car purchases.
Overall I am very happy with my new Truck.
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?

"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.

Brad did an excellent job going thru my Rogue after I had problems with it. I bought it at the Oak Creek Dealership a few days b4. I was having problems withe the front end lower plate being broken partially off. We took it to the Good Hope Dealership for service. Brad said it needed to have the bottom plate replaced and he would steam clean all the filthy mud stuck under the car. It was even wet in the spare tire compartment. Im told it now was a flood car which I just found out about. I m happy that Brad took care of the problems that should have been taken care of b4 it left the lot in Oak Creek. Thank you Brad.
Just wondering
Does anybody else’s truck just sit there after you put it drive? I have to bump the accelerator to have it go into gear. ??????????????????????????????????????????? ?????????????

Overall pleasant experience. I had some issues arise in the purchasing process, but they were all addressed timely and satisfactorily. Nice people to deal with.
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!
