All Star Buick GMC
This visit was for servicing due on my 2015 GMC Seirra, oil/filter change and tires rotation. Scheduling the appointment was as easy as a phone call and was willing to work with me at my preferred availability. Upon arriving it was a pleasure meeting Katy in the service center, whom I've known and trusted throughout the years of service since purchasing this truck from this dealership under a different owner. Seeing her for me is a testimony to her dedication to customer satisfaction and loyalty to the functionality of this department. I have always been treated respectfully, courteously and made to feel like a valved person and customer.

GMC Sierra SLT
My overall experience was excellent! Sales were not pushing, GM financial had great rates. And Allstar work with me to get what I needed in my vehicle. Easiest car purchase I have every made. I have dealt with Nissian, Toyota, and Cadillac, Allstart was by far best!
Awsome
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!

2022 GMC Sierra SLT 3.0 Duramax
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!

2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

Like the truck but also disappointed
Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

HAPPY Customer and forever Customer
I was looking for a very specific vehicle with a set price I wanted to spend and cash in hand for the down payment. As always car buying is a hectic process. The customer wants a deal and the dealership wants to turn profit as much as possible. I worked with Jared Lyons and everything was a breeze. I told him my buying parameters and asked him straight up if it worked. He told me yes and proved it, I was in and out in 2 hours with the exact vehicle I wanted. The customer service was great and all the staff I interacted with were pleasant and welcoming. I really liked the updated technology that streamlined the paperwork process. I couldn’t be happier and I plan on making this my premier dealership for my next vehicle.
Beautiful Truck
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!

Navarre GMC
What an awesome experience! The salesmen and women were great. I felt like a family member. I looked at vehicles at several Navarre dealerships, and every one of them were fantastic to deal with!
Awesome car!
Awesome car! Reliable and I have 200,000 miles on mine and never had a major repair. Comfortable. Good for towing. Easy to hold a lot of people. Speaker quality is good. I’ve owned about 6 different cars and this is my favorite by far.

Worth the wait to finally have it
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" GMC Truck!
I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

I bought my truck from a different dealer and have had to
I bought my truck from a different dealer and have had to argue and fight with them to get them to do any under warranty repairs on the truck. Patrick vice advised me to bring it into Navarre GMC and speak with chelsy in the service dept. She handled everything wonderfully her team found the problem and she lined everything up seamlessly. My truck was repaired and i definetly will recommend this dealership to anyone looking to buy or cant get any satisfaction at other dealerships service dept.
