Used GMC cars for sale near Altamonte Springs, FL

I wanted to take time to thank Rudy for being so patient and helping me find a vehicle when I needed it the most.

I highly recommend this car dealer to everyone. The entire team very professional I will definitely be coming back and purchase cars from this car dealer.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

The staff was very friendly and helpful. Joe Andrade did an outstanding job helping us find a car and keeping up with everything needed.

Just trade in my 2015 GMC Denali with 140000 miles on it and still holding strong at trade in best SUV I ever had upgraded to the new 2021 Denali and boy do I love this SUV from comfort to outside design just an amazing new well designed SUV.

This was a seamless experience from beginning to end. Fair price, nice people, convenient location. Happy customer.

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Good experience from start to finish. Showed me exactly what I asked for without tacking on a bunch of extras before showing me final price.

Easy purchase experience, would recommend to anyone looking for a new car. Everyone there was friendly and made the whole process as smooth as possible

EXCEPTIONAL Customer service!! I explained my concerns, they understood what I was saying and fixed everything! even what I had not mentioned. AND they only had I car for 1 day! Previously took to another dealer who had my car for 5 days and did what?? not sure cause still had issues when I drove off their lot. I will be back even if I have to drive 20 miles their level of great service is worth it! I have recommended Orange Buick to friends.

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

Dejuan was very knowledgeable and professional when he sold me my new car. I'm very satisfied.

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.

Thank you rudy for getting into this Corolla me and my family and excited to leave with it

Am in disbelief every week at the Gas Pumps. Thou a big truck, mileage per gallons are 18 +. Last week it was 22.8. This week 19.78.

Recently my dad and I purchased a used car from Alexa. She was amazing and the experience was so smooth and easy. No pressure, no fighting about price etc. Truly a great place to by a car. Ask for Alexa she is amazing.

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

Andy was so helpful and made sure I was taken care of he has the best customer service and really looks out for his customers.

Waiting for the Refreshed 2022 AT4 was well worth it! With all the manufacturing issues today, building and shipping was slow, but understandable. Love the truck and the features! Fit is perfect and quality is #1. Pricing was too high but all vehicles are running this way. You get what you pay for and this truck is perfect! I have owned many trucks and this by far is the best. The latest features are beyond most other makes and GM has thought this truck through from front to rear.

Finally a dealership that cares and also brings A1 service, Dominick derasmo is this the guy to have a look out for he is beyond great.

A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

I visited the dielership for an oil changed and was assisted by Jeannie Seville. She was extremely professional courteous and informative throughout the entire process. Everything was handled efficiently and with great attention to detail. Excellent costumer service...thank you Jeannie

Purchased new in October 2024. Total miles driven 9,276. Just completed a 4,734.2 mile trip through 9 states. Just a pleasure to drive. My wife and I were on the road 16 days, with only 8 driving days, longest day was 674 miles. Average driving speed was about 72+ miles per hour. Seat comfort was amazing, no discomfort, great considering having 4 back surgeries. Very solid on the road with little or no driving fatigue. Performance was great. Of the total miles, about 500 were in town driving and 300 miles was in 4x4 in a snow storm coming across Northern Texas in April. Average MPG was 26.4 with my best 500mile drive at 33mpg. The diesel engine is very quiet requiring me to check the tach sometimes to be sure I had pressed the off button. Very quiet on the road as well. This is my first diesel and I would highly recommend it. Plenty of power, great fuel economy, quiet and very responsive when you need that quick acceleration. amazingly nimble for a big SUV. The adaptive cruise works great. My previous GMC was a 2009, 6.2L V8 Yukon XL. I drove that one 140K miles over 14 years with nothing but routine maintenance, a great vehicle as well. Very happy with this 2024

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

Had my 2023 gladiator serviced in December 2025, Nash was my advisor and he did an excellent job. Highly recommended this dealership.

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

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!

I bought a 2019 GMC Sierra Elevation. I traded in a FULLY loaded 2015 Sierra SLT, that I was really sad to see go, but the Elevation really sold me on styling and ride quality. I lost a couple high end bells and whistles, but the overall performance and look of the truck make up for it big time!

Tom, in service, is very thorough. His team along with Mac and the parts department always go above and beyond to take care of my needs.

This truck has a jerk when changing gears sometimes. I enjoy the truck overall easy to handle and comfortable. Drive with ease sight is good when driving.

I extremely appreciate Bryan Olivares, he was very attentive, thoughtful and considerate to my concerns.

Excellent service. Paul was really good explaining everything happening with the car. I like the recommendation of care that I have to have done to the car.

Tony provided excellent customer service. His actively listening to my wants along with his extensive knowledge of the vehicle help him pick out perfect vehicle for me.

Any reviews on this vehicle is not correct. We are first owners and it’s been an excellent truck. We hate to see it go !

Wished they could update the inventory to reflect more accurately. The car was not available.

It was such a good truck honstly the greatest thing I have ever drove in my entire life I am so happy that I have been blessed with this being my first ever car
