Used 2021 GMC Sierra 2500 trucks for sale near Orlando, FL

I had a great experience with Sharon Munoz. She was incredibly patient and a pleasure to work with.

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!

Madison was very helpful and very consistent in her efforts and checking on my current interest. She is a very good sales person.

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

Our salesman Mike did a great job listening to us and finding the vehicle we were looking for with all the options we wanted. The whole process was easy and stress free. I would recommend Mike to a friend because of how great he worked with us.

This is the first diesel I have owned. The power is amazing and I really like the room inside the cab. This truck is a beast... Love it!

Great experience. It was fun. Got what we wanted at a good price. Truck had a lot of cool features and they took the time to show me how they worked

I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Willem was extremely professional and made an easy transaction. Rachel followed up three times to make sure I was satisfied. Great team to work with

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

I really liked everyone there that we met. When I drove the Jeep home Steve even was talking about maybe trading the truck in later. Mike was really a great salesman, I would give him 6 stars.

Jaime was very helpful with the buying process along with others that assisted us. Thank you so much for helping us with a smooth and quick process.

David was excellent to work with, he was very knowledgeable about the Equinox and was able to answer all my questions. He made going through all the paperwork easy and we will definitely want to work with him again.

I have purchased many vehicles from Mcmullen Ford. They are always friendly and professional. They treat me fairly on the price. They deliver my vehicle to me.

I've purchased probably 20 new vehicles in my life thus far. This was the best purchase experience I've had to date. Dan, Kasey and the service team were exceptionally patient...I had a lot of questions. The service team was also exceptionally helpful as well answering some very detailed and specific questions with respect to the vehicle I was purchasing. I have always liked GM vehicles but having a great dealer to stand behind the product is more important than anything to me. The facility is state of the art and I like that but the people seem genuinely interested in doing right by me. If they continue to treat me as they have I will have little reason to ever look anywhere else for a vehicle. Really a great purchase experience and a really good deal as well.

Staff were very kind and the job was completed in a timely and reasonable manner.

Garfield Sang provided a great used car buying experience. He was knowledgeable and honest and took time to answer all of our questions.

Quick buying process through online site. Sales team was helpful and quick to get me out the door. I was pleased

Mike Rose was our hero when we were looking for a almost new Tahoe. We were in Hickory and Morganton area, we were looking at a Tahoe at another Large dealer in Hickory, they SOLD it while we were looking! Called Mike Rose at Parks GMC and he took our name and number late February, 3rd He told us what he had on the lot and held it for us overnight. We arrived Feb 4th. to look at the 2025 Tahoe, High Country. We agreed on price and we drove it home. Love Mike Rose's attention to detail, southern charm, very nice, going above and beyond to help us. He was patient teaching us the new buttons and devices on the High Country Tahoe. We will purchase another new vehicle from him next week. People are important! Mike listened and treated us with respect and Southern Hospitality when we were looking for a vehicle.

And I also like to give a big shout out to the finance manager Mr. Garcia. He was a big help getting my payment down a little more. He had a great personality and we love speaking with him overall. I had a actually fantastic carbine experience. Thank you Mr. Garcia

I had a great experience coming in for an oil change. The drop-off process was quick and convenient, and they even offered me a ride to work, which I appreciated, although my job is close enough that I chose to walk. My appointment was at 9:00 AM, but I dropped my car off at 8:00 AM before heading to work, and by 10:15 AM they had already called to let me know it was finished. The service was fast, efficient, and everyone was very friendly. I have always been treated wonderfully anytime I?ve had my vehicle serviced here. Highly recommend! ?????

​"I just picked up a 2026 GMC Sierra 1500 Denali Ultimate from Ed Martin Buick GMC, and I couldn't be happier with the experience. Arthur-Zarddy Gwion Jr. was phenomenal to work with. He treated the whole process with the level of professionalism you’d expect when buying a flagship truck. He was transparent, knowledgeable about the new tech, and made sure every detail was perfect. If you’re looking for a high-end vehicle and want a high-end experience to match, go see Arthur!"
