Fabulous experience from beginning to end.
Fabulous experience from beginning to end. Ron Martin was welcoming and truly interested in helping me find the car I wanted. His friendly - no pressure approach made the car buying experience easy and fun.

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.

Good afternoon everyone, yes, I’m a lady and I’m an owner of a 2017 GMC Sierra 1500 Denali, it has a V8 motor fully loaded sunroof & also it has heated seats & steering wheel for the cold winter months & in those hot summer months you have A/C seats nothing better than that am I correct? It’s been times like that wouldnt trade for the world!! So for all you ladies who think BIG TRUCKS are just for men, go out there & buy one have them put on some electronic slide in/out rails & go out & show the shows the boss!! lol 😄 I’m out looking for a new one now either a 2500/3500 pearl white

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 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.

I recently had the pleasure of purchasing a car from
I recently had the pleasure of purchasing a car from Suntrup Kia South, and I can’t express how satisfied I am with the experience. Despite being a thousand miles away, their professionalism, transparency, and warmth made me feel right at home. From the moment I connected with Moe Saad, I knew I was in good hands. Moe exemplified the epitome of a top-notch car salesman, providing me with reassurance and guidance every step of the way. My search for the perfect EV9 led me to many dealerships, but none matched the integrity and authenticity of Suntrup Kia South. Moe and his team went above and beyond, offering red carpet treatment without the need for an actual red carpet. Even while under the weather, Moe ensured a seamless transaction, passing the baton to Dzenis, who continued the stellar customer service. From start to finish, every detail was meticulously handled, including a thoughtful conversation with sales manager Dave, who ensured my satisfaction was met at every turn. In an industry often plagued by deceit and gimmicks, Suntrup Kia South stands out as a beacon of honesty and excellence. It’s rare to find such a level of service and transparency, and I can confidently say this was the best car-buying experience I’ve ever had. Despite the distance, I’d make the journey again without hesitation. If you’re in the market for an EV9 or any vehicle, do yourself a favor and visit Suntrup Kia South. You won’t be disappointed. Hats off to Moe, Dzenis, Dave, and the entire team for exceeding expectations and setting the bar high for customer satisfaction.

Buy one if you can afford it
Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Went to look at a Rav 4.
Went to look at a Rav 4. IT greeted me and asked what options were important to me. He answered my questions and explained everything to me. The financing part was painless. IT set up my phone for me and explained all the features of the car and showed me how they work. I did not feel pressure and the entire experience only took about 2 1/2 hours. I hope that my service experience goes as well.
Nicest, best performing truck I've ever owned
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.
