Used GMC Sierra 2500 Denali for sale near Mango, FL

Demetrios delivered the most pleasant experience! Thank you so much for all of your help!

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Our experiences at Tasca have always been easy and pleasant. The service department is helpful and efficient. We have worked with Michael and Dennis and both are great! Getting your car serviced is not something most people look forward to, but these two make it easy, take the time to explain everything, and are very trustworthy.

I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

We had a great experience with Lexus of Tampa Bay, the staff (Evin Davis & Abdiel Ortiz) were friendly, polite, professional, and genuinely helpful without any pressure. They took the time to walk us through all the options, trims, and packages, making sure we were making the right choice that best fit our needs. Even after the purchase, the dealership followed up to make sure we were completely satisfied.

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Juwal, Travis and financing or seamless and didn’t harass us to add add-ons because I told what my budget was upfront and when I needed the car to do and they found that car and they made it fit my budget and I’m talking about cash budget out the door cause I don’t do car payments They are lovely lovely people they’ve called to check on the car and me and my daughter because we need the car for the safety features because of our medical issues this dealership treats you as though you are family which is greatly appreciated in a really cruel world.

I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Benny was great and the pricing was great. Price was very good. Management was sketchy at best.

Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

The salesmen that helped me was really nice and had good customer service experience. I was not interested though in the car.

efficient and professional. I purchased a fabulous pre owned vehicle from an internet ad and was able to come down, trade my car in and leave with my purchase in just a few hours!

So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Very nice The lady at the counter was super great. The service department found a problem that I was not aware of.

The staff was nice and very helpful. Jerry Ulm is very personable and sweet. They made the car buying process easy. I will definitely return to buy my next car. Special thanks you to Yazzy for making this process a pleasure

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Had an amazing experience buying my 2025 Buick Envision from this dealership! Everyone was so nice and helpful!

We brought our car in for service today 8/16/25 our service advisor John Kidd was wonderful, he kept us informed on everything, John is very knowledgeable and an asset to your company. Thank you John,for all your hard work.see you next visit Doreen Gaeta

Love this place. Great cars at a great price. Ask for claudia shes the best

Buying our vehicle at Kelley Buick GMC was a great experience. Our Sales Consultant Braxton Nyland was waiting for us with the vehicle ready to test drive. We loved the vehicle and proceeded to the showroom to work out the details. To our surprise everything was up front and open, no exhausting back and forth. The General Sales Manager Brandon Wundrow also checked to make sure we had everything we needed and thanked us for our business! In no time our new vehicle was ready to drive off the lot!

What a gorgeous truck, runs good, sounds good and has all of the amenities I need although I am looking forward to their next interior upgrade.

I would recommend Carheroes to anyone. The whole experience with them was great. They worked quickly and smoothly to get the deal done without any hassle. Thanks to Rob, Zach, and Patrick!

Love my GMC. Owned a Chevy and this absolutely beats it hands down. Never had any issues. Inside is very comfortable and can't imagine driving anything else

Great power and yet great economy. Love the safety features with the cameras and side vehicle warning. Camera that shows side of vehicle, including trailer when turn signal is on is great. Also appreciate the bed camera for hooking up gooseneck trailer.

I had an excellent experience at Kelley Buick GMC. From start to finish, the team treated me with professionalism, honesty, and respect. They took the time to answer all my questions, walked me through every detail without pressure, and made sure I got exactly what I was looking for. A special thanks to Gustavo Sanchez and Russell Hernandez — both went above and beyond to make sure the entire process was smooth and stress-free. They were knowledgeable, patient, and genuinely cared about finding the best fit for me. The finance process was straightforward, the dealership was clean and welcoming, and I never once felt rushed or “sold.” If you’re looking for a dealership that values customer service and treats you right, Kelley Buick GMC is the place to go. I’ll definitely be back for my next vehicle.

Wonderful truck. Has had zero problems. I am trading for a new one. Truck is all original with no modifications. Truck is in excellent condition.

Rudy was Great got me the truck of my dreams. Go see my dude Rudy

I've owned my truck for nine years now it is never once let me down. I'm about to put my first set a tires on it and brakes other than that I don't plan on getting rid of it it's never let me down and after reading all the other reviews it makes me realize they don't make them like they used to as they used too!

Highly recommend Rivard GMC Buick. Haley was our sales consultant, and provided a no pressure, no games sales experience. Straight forward pricing, without all the money making add ons. Family owned business as well.

I worked with Jake Thompson and if there was any heavy lifting to do during the sales process, he did it. It was no doubt the easiest purchase of a car that I have ever made. Thanks Jake!

When looking at price point vise equipment, This is your truck. I looked at every 2500/3500 on the market, same vehicle equipment and price. I chose the Duramax.. HP, Torque of this Diesel, truck equipment that the SLT price point had everything that I wanted for safety, appearance and comfort, none other came close. This is your truck...

My salesman was Mike, and he was very helpful, and we bought the GMC from him.
