This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

Best service around
Great service. Friendly people! And can feel they care about me and my vehicle!
Updated model
Read many reviews and researched this vehicle and that helped me decide on this vehicle. Traded in a older suburban for this updated Yukon. Look forward to driving it.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

My experience at AutoNation Chevrolet Pembroke Pines was
My experience at AutoNation Chevrolet Pembroke Pines was nothing short of amazing! I had the absolute pleasure of working with Damiar Pennant, who went above and beyond to make sure I felt comfortable, informed, and confident in my purchase. He took his time explaining every feature, detail, and mile — and even gave me a tour so I’d know exactly where to go for future oil changes and service visits. After a terrible experience at another dealership (Kia Hollywood), I walked into AutoNation feeling nervous, but both Damiar and Alex, the sales manager, completely changed that. They worked together with such professionalism, kindness, and care that I left not only satisfied but truly blessed. They made the entire process smooth and stress-free, and for that, they deserve a standing ovation. Thank you, AutoNation Chevy of Pembroke Pines — you’ve earned a lifelong customer! 💙🚘
Beautiful riding truck
Love the truck, lots of bells and whistles, smooth ride, satin Steele is a beautiful color. The Denali has lots of space for my four boys.

Ricardo Rutledge was a great sales consultant!
Ricardo Rutledge was a great sales consultant! He cared about my daughter’s safety with her becoming a new mom and selected the best vehicle with the options that fit her! He answered all of our questions and went above and beyond. Highly recommend this company. We currently have 2 loans through GMC. Never had any issues. They replace the FOB batteries for free anytime they get low on battery.

I recently purchased the 2025 Pathfinder Rock Creek from
I recently purchased the 2025 Pathfinder Rock Creek from Victory Nissan of Nashville, and I couldn’t be happier! Not only did I get an amazing deal, but the customer service was truly top-notch. Mr. Matt, the manager, was incredibly professional, helpful, and genuinely a great person. What stood out the most was his trust and hospitality—he even let me take the vehicle to a restaurant with my family before any paperwork was done. That showed me how much they care about building trust with their customers. I also traded in my Nissan Altima, and to my surprise, Matt gave me an excellent value—better than I ever expected. Mrs. Shelby was also wonderful; she took the time to thoroughly explain the vehicle’s features and condition. If you’re looking for the best deal and exceptional customer service, I highly recommend Victory Nissan of Nashville. I’m thrilled with my new Pathfinder and even more impressed by the people who helped make it happen!

I had a top-notch car buying experience at Lamarque Ford! My salesman, Kyran, was awesome?super down-to-earth, knowledgeable, and very patient throughout the entire process. The financial aspect, which can often be stressful, was also smooth and straightforward. I would definitely buy from Lamarque again in the future. Absolutely love my new Bronco Sport!!!
