Joe is great as well as all the people I interacted with at the dealership. They all were very friendly and professional. I appreciate Joe getting me the best deal possible with this being a second car loan.

I saw this car driving by the dealership and automatically was drawn to it because of its color. GMC calls it brown but one print out called it crystal metallic purple. It changes colors depending on the weather. I love the handling, the dash and all the bells and whistles! My grandchildren love how much room that it has!

The Best Ford Dealer in St Louis area
This Service Department saved my sanity. I had an issue on a new Ford Focus that no other service department in area could even locate, tried 2 other service departments including original dealer car was purchased from. They found it and fixed it in 2 days.
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

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.

I always bought the GMC Acadia (4 times) but decided to try the terrain. I absolutely love it and it's a great car for zipping around in town. I would take it for a weekend trip but not on a long trip as it doesn't have a lot of cab room, but for two people it is fine

Excellent service by the whole team.
Excellent service by the whole team. They worked on my car was finished sooner than I expected. The service manager was outstanding. The work was done professionally and the car was even washed. I highly recommend the dealership. The waiting area, features, free water, free coffee, comfortable chairs, and tables and very clean and bright
I have owned my Acadia just under one year.
I have owned my Acadia just under one year. It is quiet, stylish, has an easy and very effective infotainment system, owns five star safety and shows every indication of being as reliable as the Yukon I owned for 20 years. This Suv will go to 60 mph in about 6.0 seconds flat. It has 20 inch wheels and tires and will turn better and stop faster than most every Suv. I have front and rear heated seats, cooled seats, a sunroof, memory settings and this is only an SLT. My gas mileage routinely exceeds EPA (with AWD). Driving from Milwaukee to Chicago, I averaged 29.8 MPG at 75 mph. EPA is 26 MPG at 65 mph. I truly LOVE that Car and Driver rates this SUV near the bottom. Better for me. I have the Home Run. The OWNERS of the GMC Acadia rate this SUV higher than Highlander Palisade, Explorer, Telluride and all the rest. Count me among them. FYI, not a GM employee, just a happy customer.

Easy Car Buying Experience
Great overall experience. Easy car buying experience. Friendly knowledgeable staff.
Good car only some issues
Have had lots of problems with the wheel sensors. New tires and new sensors and still have the same issue. Shows tire low and it is not. Just car not even two years the air conditioning would not blow out cold air. The compressor in the back went out, need to be replaced. Side car waring lights come on sometimes even though no car anywhere near me. Fold in mirrors are a joke the driver side comes in and out, however the passenger side sticks. Dealer said yeah that happens. This car is garage kept!

Excellent Service!!
I was in an accident and my car was totaled. I wanted to replace it with a new Nissan Rogue, it the car dealership that I got my last one at was no very anxious to help me find one since I hadn’t received the check from th insurance co. yet. Todd Eversgerd went out of his way to find a car, get the extras that we wanted installed on it, kept in contact with me re: when the car was delivered and the work was done, etc. He even went so far as to try to match the color of paint on the number of our license plate that had been scraped off during the accident! Eva’s very professional and went above and beyond in all aspects. When we got there, he was busy with someone else across the street at the VW dealership, so he had Matt help us wile he was over there. Matt also was excellent. He went over everything that Todd had written down including giving us the manuals, having us watch the videos, introducing us to the finance manager. Afterward,Matt took us out to the car went over everything about the car,and programmed our phones into the car. He then called Todd so Todd could make sure we didn’t have any other questions. I have never had anyone go to the lengths that stood went to make car buying so easy.Will definitely be back for our next car!

Bought the car CPO in summer 2021 with 38k miles.
Bought the car CPO in summer 2021 with 38k miles. Now being summer 2024 with 90k miles and I’ve mostly had good luck with the car and its components. I have the extended warranty through 100k miles but I feel like all American cars are built to fail after the warranty runs out. Overall great car: I have the 2.0L turbo engine with 9 speed auto and AWD. AWD is great when turned on, grips the road well, and to be honest the 2.0L has a TON of power; way more than you need for a compact SUV! I had a quick issue around 65k miles where the service traction control and stability light came on for 15 minutes. Dismissed itself and haven’t had an issue since. At 75k miles, it was during the winter time, the car would display “park break realized” and “service traction control” when the auto start stop would kick back on (there’s no way to shut off the auto start/stop system). No issues and lights but the messages would pop up and dismiss themselves. Little did I know it was my battery dying and my mechanic said “some wires were loose” and he tightened them up. Haven't had an issue since I got a new battery. Last thing that happens is sometimes when you have Apple CarPlay going and you unplug the phone, the infotainment system will freeze and no Bluetooth, usb, or CarPlay will work for the reming duration of the ride unless you stop the car and let it sit for at least 30 minutes. Simply shutting it off and turning it back on never worked. Overall I give this car a good rating for 0-100k miles. I am pleased with the car but looking for something bigger soon. I think I did overpay a bit for it ($30k for 38k miles) since I got it summer of 2021 when new cars were nonexistent!

I had an excellent experience working with Rodney Brown. From the very beginning he was knowledgeable, attentive, and genuinely interested in helping me find the right truck. He provided clear, honest recommendations, and I never felt pressured to make a purchase.

I bought this truck new 8 years ago (and 77k miles). I use this truck for truck things like towing a 5,200lb trailer @8 times a year. The V6 has plenty of power and gets good mileage (22 mpg combined, 29 highway empty, 15 pulling the trailer). Reliability has been outstanding. The transmission needs a full flush about every 40k to keep it shifting smoothly. Other than that this truck has been without issue.

Great Truck
GMC Canyon Denali with the 2.7 Duramax diesel is a loaded power house with great fuel economy. 4x4 has a towing capacity of 7000 pounds, the best in class. 31 MPG on the highway! Previously owned a Tacoma but it would not pull our travel trailer with the V-6. Highly recommend the Canyon diesel, if you can find one!
