Used GMC Sierra 2500 trucks for sale near Mount Dora, FL

Darrin Grant was the most personable and easy going sales person! He got us what we wanted for our trade and sat with us in the back seat of the car introducing us to the car, like connecting our phones and going over the options on the dashboard. He helped us for 15 or 20 minutes. He then told us to call him from home anytime we have a question about the car and he would talk us through it. 10 out of 10!

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.

Brian did a great job. Very easy to work with. I will definitely buy from Mullinax again

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.

I ask a lot of questions, challenge any information that doesn?t make sense to me and expect honest, timely and transparent communication from the service provider. Latonya and the Orange Buick Service and Parts team exceeded my expectations! This was my first visit and happy that I have a trusted partner with my new-to-me Yukon XL.

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.

This is the second car I buy here and they have always taken good care of me. Nice, friendly sales people and they work with you on finance options.

I traveled to Gibson’s Truck World to purchase a truck for personal use, and was pleased with not only my choice, but with everyone at Gibson’s....I will buy my next truck from them as well

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.

Arturo Reyes and Steve help me get my dream car and I appreciate it I highly recommend winter park auto exchange

I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

Extremely profesional and knowledgeable! No xx dealership! I highly recommend them!! I visited the dealership and appraised (based on milage and real condition of the car), once I had the correct value for the car and interest rate for financing, I made my offer, and once they confirmed the numbers, we made the deal in less than 15 minutes! I did visit a few dealerships were I wasted my time! Some dealerships don’t take the time to look at garbage they are selling. They go by time on the lot, the make and models and average market sale price not really looking into the real condition of the car. All the information I needed is easily accessible, if you know where to look. I deal with facts not averages!

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.

I bought a vehicle from Orlando Preowned. I am from Minnesota. Nathan is fantastic. Great communication. Financing went smooth. Couldn’t have asked for a better experience.

Just the truck I was dreaming. Auto world experience is great on product knowledge high recommend 2500 Hdz Denali truck you won’t regretted price product and drive experience

Good, friendly, cordial, timely, excellent. We just couldn’t agree on a value of the vehicle I was interested in.

Very courteous and explained everything I needed to know. Purchased the car from Daniel who did a great job getting us on our way.

Purchased a 2026 Sierra, and had an excellent sales advisor, Will Pardee. He went above and beyond to make this a great purchase experience. This included the trade-in process

Started off my vehicle search at Mullinax Ford and visited 5 other Ford Dealers over a 4 day period. After the search was over, Mullinax Ford had the best deal for my new vehicle, the best deal on my trade in, best customer service and best selection to choose from. The entire team at Mullinax Ford was awesome to work with and didn’t play games like some of the others. Great Experience….Thank You!

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!

This place is Amazing! We literally jumped from truck to truck to narrow down or choice. To be able to go to one place and have so many options, this was perfect.

Steve B and arturo reyes made my car buying experience great i was scare but they explained me everything and help me get a good deal

I drove to Crown Buick GMC after making an appointment with Tammy Wagner. She was a new sales person. Tammy is very patient. She enjoys people and made me feel comfortable. I had alot of questions about my new All Terrain Truck. When she didn't know the answer- she was honest. (thats important to me) They , Tammy Wagner and Mike Mathis her manager sold me the truck of my dreams. I plan to be a life long customer with Tammy Wagner at Crown Buick

What a great experience with William Martinez! I drove 4 hours to get my new truck and it was so painless. I’ll be back here to deal with Will and his Truck expert team again!

Without a doubt a good dealership to do business with. They handled my sale professionally in every way. . Absolutely no pressure and they were honest with me unlike the previous dealership I had dealt with. In particular Jeff A. did a great job making us feel comfortable with our purchase. I highly recommend this dealership.

We had the pleasure of working with your salesman Zach Adams today! He was very professional, helpful and made buying our vehicle much easier & faster. Zach handled everything from showing us the truck, personally cleaning it and all financial paperwork. He went above & beyond to make sure we were satisfied customers!!

Michael in service department is just awesome. He takes care of us as if we were family. I wish everyone would deal with us like that. Some businesses act like we are bothering them for them to take our money. Anyway, I could go on and on. Even Pete the sales manager is a great guy, and greets us in the waiting room like a friend. This dealership is what you strive to have represent GM. I am retired US Navy and appreciate respect and curtesy. Thanks Del

Roy was a great salesmen. The truck was detailed and filled up ready to go. Sales was smooth and stress free. Thanks Roy!

The folks at the dealership were friendly and efficient. It was a completely pain free experience!
