Used GMC cars for sale near Flandreau, SD

Had a good price on the new truck, and gave a good trade in price. Didn't try to low ball me on my trade in.

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!

Professional and helpful in the service department

I love my car. I love the way it handles, and the confidence I have in it when I’m on the road. The room in it is fantastic. All the room I need for when we travel.

John did an outstanding job getting me in and then diagnosing the issue with my 2021 GMC 2500 Denali. The work was completed quickly.

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.

BAM didn?t have the inventory that I was looking for. They worked with me to help find me the truck I was looking for. They offered a policy that offers no deductible on my windshield. I was so happy with the hometown service I received and will gladly do this all over with BAM!

On my 7th one. That should say it all. Quality crafted, full of great features, super smooth ride and plenty of room for up to 8 people plus a ton of gear.

I called in a truck and asked the salesman some questions. He was pretty helpful until I asked him about the check engine light. He said he didn’t know if there was a check engine light or if there was, what the code(s) might be. I loved the truck and had cash, but decided not to drive an hour one way without having more solid information. I was disappointed.

Great truck to own. The 2023 GMC Sierra Denali with the 6.2L engine delivers excellent power, smooth performance, and a refined driving experience. The ride quality, interior comfort, and overall build quality are outstanding. I have had no issues whatsoever, and it has been a reliable, enjoyable vehicle from day one. I would highly recommend it to anyone looking for a premium full-size 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 had my Denali XL for two years and absolutely loved it. It was comfortable, quiet and handled well for a large car. My only complaint was gas mileage. I made two trips to Las Vegas for bowling tournaments with all of my bowling gear and my dad's gear plus our luggage and got it all behind the third row seat. I loved all the bells and whistles, especially the cooled seats in Las Vegas. I'm actually thinking about buying another one now that my frequent trips are over. But it can be difficult to justify the expense of this monster. $80K fully loaded is a lot of money for a family wagon. Even used they're expensive.

The best and easiest car buying experience and customer service. I was car shopping in Fargo, ND, but thankful we found the car we wanted at DeBoer. We drove 5 hours to the dealership and it was worth it! We highly recommend!

I bought this GMC Sierra about 5 years ago and only had to change the battery, tires, and oil change. Dependable. Everyone wants to buy my truck but I'm in the process of details on outside doors. Being a woman with a V8 like this, I get around. Excellent truck!
