Used 2018 GMC Sierra 3500 Denali trucks for sale near me

Great salesmanship! Willy helped us seal the deal efficiently. ❤️ our new CR-V. Mountaineer Honda Rocks!

An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

The sales associate Shayla was friendly, knowledgeable and professional. The test drive of the vehicle was informative

Just what I was looking for and the price was right. The color was the same as the truck I traded in. We have purchased a bumper pull camper and now mountain passes will feel like flat roads!!

Meaghan Mansfield is the best, as always. I always know my vehicles and I are in the right hands with her.

This is my first HEAVY DUTY truck and my first diesel. I have only had it a week and 3 days but it has already been on the job and been driven 1500 miles. I expected a much rougher ride than the Chevrolet 1/2 ton it replaced but must say I am pleasantly surprised. I compared ride quality to it's main HD competitors and this GMC 3500HD surpasses them. It has far more tech features than should be expected in a base model but I can appreciate the convenience especially for business. I love that it will project driving maps and directions from my iPhone onto its larger screen. I have not yet towed or seriously taxed its payload but the Duramax diesel is something to behold. Averaging 17.9 mpg over 1500 miles. The DEF fill could be a bit more convenient but putting it under the hood does keep DEF away from fuel filling and is not required often enough to be an issue.

I felt they were honest 1st of all. Can't say that about very many dealerships. They gave the best trade-in value on my 2015 Tahoe (by far). I searched Missouri and Illinois for about 8 weeks and Sapaugh was the best experience Hands-Down. My ONLY fault with my whole experience was getting my paper work finished. It was a cash deal with a trade-in. NO financing needed. But it was a holiday weekend (01/02/2026) only one guy doing the paperwork processing instead of two. NOT a giant deal.

The Denali version is absolutely what we was looking for. Towing capacity is awesome. Has plenty of room in back for kids or cargo. Would recommend this vehicle for anyone who tows trailers. Duramax is what they say it is with Allison transmission best vehicle on the market.

Colby Kluck rocks! He was amazing to work with and knows his stuff very well!

Drove well and plenty of power, the SLT is perfect for us with the 40-20-40 front seat and without the extras that we don't need that are on the Denali.

James Peters was so helpful. He went above and beyond to help me. And I recommend him to anybody looking to buy a car.

By far the BEST dealership I have EVER worked with while purchasing a vehicle! We bought a Silverado High Country back in NOV and it is AMAZING! Rocco and the Team at the dealership were so patient with me as I was test-driving and they were very helpful with all the questions I asked! And the truck is AWESOME!!! Been a dream to drive and I will be eternally grateful to Rocco and Platinum for a fantastic experience!!! I will be a FOREVER Platinum customer!!!

Great place to buy used cars. The sales person Leon was helpful and make the process smooth and efficient. The finance was surprisingly fast. It was a great experience.

Best service and sales team in Sauk Valley! Service is always so kind and informative, the sales team is always very accommodating and a pleasure to work with. 10 out of 10! Would recommend them to anyone.

We had a wonderful experience at Unique Auto Group. We found the vehicle online and called to say we were interested. They had the vehicle pulled out and ready. The price was excellent and as advertised. No hidden fees or problems. Amir was great! He helped through the sales process, and everything went without issues. I highly recommend buying a vehicle from Unique Auto Group! We will definitely buy from them again!

I have been a customer for about 12 years. The dealership has sold me 2 compact cars. One truck and a 2016 Chev Equnox. This car has been my favorite. This dealer is the best in the State. I have all repairs and maintenance done there. They are superbly courteous to customers and do excellent work. I always get my vehicle back when promised and the have always done the work I have requested. I will continue to purchase my vehicles from Salt Lake Valley Chevrolet. Thank you from a very satisfied customer Sincerely. Stan Parkin

We purchased our Ford F350 about a month ago for a great price with absolutely no pressure or hassles from anybody there. They took our old F150 in trade and delivered the new truck down to Colorado Springs. Mike replaced the cracked windshield before delivery which we hadn't asked for or expected, which was awesome. Already put a hard 5,000 miles on it pulling a very heavy 5th wheel RV trailor in a across country move. The truck performed great and we absolutely love it!

Buying my 2021 Black Widow F-150 was an incredible experience thanks to Tim and Travis. From the very beginning, Tim showed genuine warmth and hospitality—he even picked me up from the airport himself! His professionalism, honesty, and friendly personality made the entire buying process smooth and enjoyable. Travis, the sales manager, went above and beyond to make sure I was taken care of every step of the way. He made the process easy, transparent, and stress-free, ensuring I got exactly what I wanted. Both Tim and Travis made me feel like more than just a customer—they treated me like family. I’m beyond thrilled with my new Black Widow F-150 and the amazing service I received. Tim and Travis have earned a customer for life, and I’m proud to now call them lifelong friends. If you’re looking for top-notch service, genuine care, and an unbeatable experience, these are the people to see!

The salesman was very helpful and went out of the way to help me on this deal. I greatly appreciate his help. I would buy another vehicle from this location and not hesitate to recommend people their way. Again I thank Luis and the people at this location. Keep up the good work!

Dealing with the sales person was an excellent experience! It so nice having a fellow VET helping me with the process. My son is so pleased with his new car! Now he has to pay me for it. Lol

Can never say enough about how glad I am that I chose to return to Thompson's for my second GMC purchase. The first time Bobby D. was so helpful that I requested him 2 years later when I returned. He does not pressure you. He finds out what you are interested in and why, how will you use it? He then gives you options that are available. He was able to answer all kinds of questions about how the vehicle operated etc. He is so likeable. I wish everyone who deals with the public was as polite, understanding, knowledgeable and on and on as he is. THANK YOU BOBBY! Oh Yeah, I like my 2 vehicles too!!

Randy was excellent to work with. Easy to get paperwork completed. Felt we got a good deal
