I've been looking at Aviators since 2021.
I've been looking at Aviators since 2021. After getting screwed around by several other dealers, one phone call to John Newman and I had my Aviator within 2 months.
I own a 2023 Sierra 1500 Elevation equipped with the 2.
I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!
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!

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.

I needed a new vehicle and had decided to upgrade from my
I needed a new vehicle and had decided to upgrade from my previous cars. A Cadillac was on my short list, so we started with Napleton Cadillac in Rockford. As we were looking at the cars, we were greeted by Alex, who brought us into the showroom to chat so he could find out more about us and what we were looking for. We took a beautiful new XT5 out for a test drive, and then went back in to chat more and get more information. I told Alex that I was just beginning my search, and he very nicely asked if he could give me a card, which of course, I took. Over the weekend he emailed me to explain current offers and rebates. After looking at a few other brands, I decided on an XT5, so we went in the following week to further discuss a purchase and look at a few new and preowned cars. Alex took the time to explain the specs on each one, making sure that I understood what each car had to offer. He wanted to make sure that I would be happy with the model I chose. Buying a car is a long process, but the Napleton showroom is very comfortable, and the fresh coffee and snacks kept us going! By the time we finished with the purchase, night had fallen and I wasn't comfortable driving a new car in the dark. Alex offered to have it delivered the next day. My beautiful new XT5 arrived the next morning at the appointed hour, freshly washed and detailed. Alex stayed to help us set up our Onstar service and get acquainted with my car. The overall service was simply impeccable. From the beginning to the end, I never felt any pressure, and everyone at Napleton made us feel very important and welcome. I am very happy that I chose to shop locally and that I chose this dealership. I want to thank Alex for making the whole process easy and pleasant. Five Stars!
"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.

I am happy with the service overall.
I am happy with the service overall. However the service took longer then it should have. I had back to back appointments that morning so I called they day before to make sure my oil change and tire rotation wouldn't take longer then expected. The gentleman I spoke with assured me it would be no longer then an hour. When I checked the vehicle in I asked again and was told they would have me out in 45minutes. I had to go ask what was going on with my vehicle after an hour and 15minutes. The gentleman at the service desk had an excuse that someone had come in late so it pushed me back. As a result I ran late for my next appointment. This was annoying and made for a stressful morning. It would help in the future if they would be honest with the customer about time frame.
