Great truck to own.
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.

My service advisor, Michael, was the best!
My service advisor, Michael, was the best! I had an inquiry about my car and he took the time to check everything and even test drive it. I then had to get a new battery and was lucky enough to reach Michael again and he got me in and out before I could get settled in the waiting room! He was very patient and personable. Great service! I highly recommend him and this dealership!

Great Experience!
Ernest helped us with purchasing our 2022 Tahoe. Ernest is patient with our questions and did everything to help us feel confident in our choice. I would recommend Fitzgerald to anyone! This was a great experience and I look forward to coming back for our next vehicle! Thank you Ernest and Team!

What a pleasant experience.
What a pleasant experience. My first time financing a vehicle. When going to initially look at the vehicle, I discovered a few issues. Obviously no used car is going to be perfect, nor was I expecting it to be. They told me to come back the next day and the issues would be fixed. I came back and they did in fact fix the car. They are willing to and have went above and beyond.
Better than my old truck
The truck has more features than I need. It is quiet and comfortable. it has plenty of power to pull a work trailer. Overall a nice truck

I bought this after going to the dealer just to look at colors. I had a 2016 Chevy 1500 LTZ that I loved. There was my down payment and took this Denali home. Only 2 options. Paint and moonroof. I thought my chevy with 3.42 gears was quick. This one goes with 3.23's. The ride is great. Fit and finish are perfect. My only complaint is this Bose/Apple play radio is not what the 2016 Bose was.

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

I own a 2023 Sierra 1500 Elevation equipped with the 2.
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. :)

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!

I recently purchased a 2025 Kia Sportage Prestige, and I
I recently purchased a 2025 Kia Sportage Prestige, and I couldn't be more pleased with the exceptional service I received from Donny. His customer service skills were outsanding-he actively listened, was incredibly knowledgeable about the vehicle, and kept me well-informed throughout the entire process. This is the third car I've purchased from this location, and I was intially unsure if the experience would match the high standards set by my former salesman who is no longer there. Donny reassured me that I was in good hands, but he was wrong-I was in great hands. I had considered other brands and wasn't certain I would stay with Kia, but Donny's patience, professionalism, and thorough answers to my (many) questions made all the difference. He was truly phenomenal, and the overall sales experience was marvelous thanks to him. Donny's outstanding service is what ultimately sealed the deal. Highly recommend asking for him if you're in the market for a vehicle! I am writing to follow up on my previous message regarding my concerns with the Finance Department. I am pleased to share that since then, the team at King Kia of Laurel has gone above and beyond to address my concerns and turn my experience into a positive one. I would especially like to recognize Larry, Carlos Mendez, and Matt Aglio for their extraordinary efforts. Their professionalism, responsiveness, and genuine commitment to customer satisfaction were truly impressive. Thanks to their support, I now feel confident and valued as a customer. I appreciate the time and care taken to ensure my concerns were resolved and that my experience ended on such a high note.
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!

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 have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Great and trustworthy team! This is my second vehicle purchased from them, and I couldn’t be happier. I’ve checked other options, but their prices are much better for the same mileage. Highly recommend these guys!”

overall i like the truck alot, its a very dependable vehicle. it has its little quirks for a used truck. there's little things like the drivers door switch for the mirrors and the door locks that are not working as of now but i haven't taken the time to look into it as of yet. minor to me and i'm sure i can fix for a few bucks. nice riding and driving truck i would buy again.

kIA K900
If my credit was on point I would've been driving my dream car. The K900 is a sleeper for those who do not know. But they did try to help.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
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.
