Used GMC cars for sale near Altamonte Springs, FL

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.

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.

We came in from out of town, the car was accurate as far as the listing, cosmetics a little worse but we got a good deal, thanks Sean

I own a 2023 Sierra 1500 Elevation equipped with the 2.7L TurboMax, and it’s been outstanding. It currently has 23,000 flawless miles. I’ll admit, I was skeptical of the 2.7 at first, but I jumped in feet-first and have never looked back. Living in Colorado, I regularly tow a 5,000-pound travel trailer through the Rockies with zero performance issues. The truck pulls confidently, handles grades with ease, and still delivers impressive fuel economy—23–24 mpg on the highway and about 18 mpg in town. I couldn’t be happier with this setup. If there is a negative to mention, that would be that after three years of ownership, the black wheels havent grown on me, and Im beginning to hate em. :) Lastly, the mpg while towing drops to 9mpg which is similar to that of a V8. All said, its been a great truck. :)

Ernesto Sosa and Carlos was amazing and got me a trade on my 2023 Chevrolet Equinox to a brand new 2026 Chevrolet Equinox. They gave me such a good deal on my purchase with a good price go to them for your purchase they’re awesome to work with. This is the second purchase here in two years and I can’t say enough good things.

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

A low pressure and friendly experience. The price negotiation was professional and not intimidating. As always go in knowing your numbers! I am hoping that the maintenance experience is as professional.

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.

Fernando and Donovan did an excellent job, from my initial inquiry to finalizing the sale. The negotiation process was painless and fair. Donovan?s military background served him well, as evidenced by treating us like family and his attention to detail. He continues to maintain contact to ensure we are happy with our purchase and to answer any questions we might have. I couldn?t be happier with the buying experience and their continued support after the sale.

2021 GMC sierra 1500, 5.3, crew cab 4x4, 21000 miles. brakepad monitor lites up. dealership says needs brakes and rotors in back. one mo. on warranty. our rural roads dirty up the monitor. Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

We love our van thank you Blake and all the time you spent with us

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

I purchased a nice used vehicle from this dealership and had a good experience. It took a bit too long to wrap up the paperwork but I guess that’s to be expected. All in all I highly recommend this dealership!

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Bart was amazing.He greeted us immediately.He was very professional and kind.We were in and out within two hours. I would definitely recommend this location to anyone who is in the market for a vehicle. 10 out of 10 service.

Let me start by saying I have the AT4 model with the Duramax 3.0L diesel. I had a 2024 Elevation with the 5.3L V-8 that I bought to pull my 22’ camper. While the Elevation pulled my camper fine it drank the gas like it was on a binge. And with a 26 gallon gas tank it seemed I was filling up every couple of hours. After one trip to Nova Scotia I knew something had to change. I pulled my camper out west to Yellowstone and back through Arizona. It pulled like a champ and fillups were a lot more manageable. Even driving the speed limit out west I still got four to five mpg better than with the gasser. I liked the Elevation but I love the AT4. Way nicer ride and great handling. I get 30 per gallon of diesel on the highway if I drive the speed limit but I got it to tow with. I added a Titian replacement fuel tank so I have 43 gallons instead of the 26 it came with.

Keven was great to work with and his team made success of a difficult situation. I give my appreciation to RC Hill and Keven for their love in trying to help in finalizing a successful transaction. Thank You.

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!

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.

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.

I’ve met many salespeople, but Ali stands in a category of his own. He doesn’t just sell cars—he creates trust. From the moment I walked in, Ali paid full attention to what I needed, offered honest guidance, and delivered an experience that felt personal rather than transactional. His professionalism, calm energy, and deep product knowledge made everything effortless. If you want not just a car, but a smooth, confident buying journey, ask for Ali. He’s the reason I’ll return—and the reason I’ll recommend this dealership to everyone I know

Brought my 6000+ mile Cross Trek in for an oil change and to check a tire for a slow leak. I brought the car in at 1000 miles and they couldn?t find the problem. I even got several emails from Subaru about the low pressure so the issue was documented. Once again they said they couldn?t find any problem. I explained that I am adding air to the tire every three days. I gave the service provider the choice of trying again or putting on a new tire at their expense and they somehow found the leak. She was a very nice person, I just couldn?t believe she/they expected me to leave with a well documented slow leak unresolved.

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.

Very pleasant salesman. Quick and painless process. Would definitely do business with them again. Got the deal we wanted.

I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Had to take my cat for a recall and as always Sara my service rep was great and professional Have been a customer from many years and have always dealt with Sara !

Okay but what is the best way you can do this for with a good price and a nice price for a decent price like this one for like two or five years and a good price for a really good quality one of the ones that I got from the

Everything went great, I went in for an oil change and they found I had a more serious problem. My car is now back at 100%. I deducted one star because the car was not cleaned as well as it has been in the past after a service.

I have enjoyed my vehicle. It is comfortable and drives very well. I like the color also. It is very roomy, takes off fast and the safety features are very beneficial.

I came in for a simple service and was greeted kindly by Nataly. Facilities were clean and amazing, even the amazing coffee machine to make my evening.

I own a 2021 Yukon Denali with 23K. At nearly $90k, I purchased every option except for the silly entertainment screens fastened to the back of the front seat headrests. (nice for leaving the imprint of your passenger's faces on the screen in an accident - buy a couple of iPads. First of all, kudos to GM engineers. Technology actually exceeds German cars I've owned. Rear view camera is GREAT and adjustable for brightness, distance and width. But, make sure you purchase the washer for the rear lens...Miirror is almost unusable in rain..(blurring with rain and dirt quickly. I'm 6'2" and really ticked-off there isn't a handle on the "A" pillar to grab to pull into the driver's seat. They put a handle at the upper center of the door opening. What is that for? I have to grab the steering wheel (fortunately rigid with the engine off). Another big problem is the loss of both knees in a frontal accident. With the steering wheel all the way back, I can't even come close to stretching my leg out. Really! A couple of bigger issues: I know the front of this vehicle is right off of the truck, but the end result of the gigantic, unsloped hood, is the inability to see anything 12 feet in front of you. And making right turns.....better memorize that curb before you start your right turn because you won't see it again. Just "that look " from your wife as you run over the curb again with your right rear wheel. Lastly, I hope someone from GM reads this.....With all the awesome high-tech items on this car, why are there no "turn" lights? You know, the lights that let you see where you're going, especially right turns. Porsche has LED lights designated for turns that light up the whole area you're turning into. In the Yukon at least I'll see what I ran over with the terrific rear view mirror! My only intermittent mechanical annoyance is when I push the door handle to lock the doors. It's supposed to fold the mirrors in which is a good way to check you locked the vehicle. occasionally , they don't fold and I have to push the button 4 times. Of course, the mechanic needs only to push the button till it works and tell me it's working. Twice. Guess they win. I'll live with it. Now for the rest: Fantastic overall vehicle! With the air suspension it rides better than Mercedes or Lexus. I always get positive remarks from passengers. The steering wheel control for the Active Cruise control is absolutely perfect. I've driven between Arizona and Colorado without taking my hands off the wheel (just moving my thumb). And the engine, I LOVE THE INLINE 3.0 DIESEL! Almost got the 6 liter but took a chance on the diesel that just came out (in 2021). Same exact torque as the V8 and great for passing. The big difference ..... I had to take a photo of my dash to prove to my friends....heading back to Phoenix with 256 miles on the odometer averaging 30.2 mpg going the speed limit! My Porsche Cayenne gets 19.6mpg (not going the speed limit). The 9 cameras help when parking unless your wife is with you. When I come to a stop I'm waiting for my wife to hold up the 1 to 10 signs like the judges in the olympics. And lastly, For a car that will raise 5" in 4 low, why does the car come with 1 ply polyester sidewalls ? I'm not comfortable on gravel or rocky roads for fear of a sidewall puncture. I highly recommend this vehicle. The designers did a great job making this big vehicle look sleek and smaller than it is. I'm a bit unnerved when I see a vehicle like mine come flying into a parking spot for a perfect 4-point landing and the driver is a 110 lb soccer mom. And I just spent 20 minutes with a micrometer adjusting my position so I don't get "that look" again from my wife. Good luck and hope it's reliable.

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

Entire process completed in one day. Big thanks to Jason the sales manager. Will definitely be back here for my next car purchase as well.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

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.

Just bought 2024 Yukon with diesel engine and drove 2000 miles and it was the best ride that I’ve had. It was comfortable, reliable fuel efficient not to mention a great looking vehicle.

A great experience overall. Everything was streamlined and run very well. High level of courtesy given to make us feel welcomed and valued

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
