I had to replace my RAV4 after 12 years and dreaded the thought of car shopping. I decided to start at Post Oak since they had done excellent work on my RAV4 in the past. Tyler Rowe was so personable in his approach my guard just dropped and we just talked. He heard what I was saying and had a car in mind for my actual needs but also had vehicle 2 and 3 lined up In his mind for me. While I looked at the exterior of the first vehicle he went to grab the keys for that test drive but also came back with the option I thought I wanted. Long story short I’m happy with his suggestion and the follow up and courtesy I experienced throughout the dealership. I want a relationship where I shop and I feel like this team agrees. Thank you Tyler and team.
An AWESOME Vehicle!
This wasn't the vehicle I'd gone to the lot to see... But it was parked 2 vehicles down, and the price was $3000 cheaper!! It even has more bells and whistles than the Toyota I'd initially planned on getting. Awesomeness!!

The gmc Yukon from 2014 is very good it’s good for snow hauling trailers and children. What I love is the cozy luxury interior with the leather seats. It is very reliable the biggest problem we had was the cooling system failing but the repair cost was only $200. I kept everything on it stock. The sound system speakers are crazy good the base is 200% good I just love everything about it!

Buying experience was spectacular. Very professional atmosphere, from the parts dept, to customer waiting area to the receptionist. Hands down the best car dealership in OKC!
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!

Its a decent car, but on a car frame. I had a GMC Envoy a truck frame SUV and it was so much nicer to sit higher than the sedans and baby SUVs on the road. Doe have nice accelerations and mileage tho.

Awesome experience.
Awesome experience. Sales manager Mel Navarette was extremely helpful, considerate, and was anything but your typical car salesman. This man listened to our needs and helped us every step of the way. The entire team was friendly and helpful. They found the financing that fit my situation , in spite of my less than great credit and small down payment. If you're looking for a good deal check out Southwest Car Sales, and ask for Mel. Nice inventory and good prices.

absolute soldier in the field, looking for a heffer hauler this sob can handle that extra tongue weight. Super cool supercharger sounds coming from the tranny but I think that was part of the luxury package.

Love Our New 2023 Denali Terrain!
We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

I purchased my 2016 GMC Terrain SLT in 2018 as a gently used vehicle with only 21,000 miles on it. I never had issues with it. I kept it regularly serviced and had to replace tires. At now over 93,000 it has been a comfortable and very reliable car. The only feature I wished it had was rear air conditioning. Living here in the SE it gets hot and it takes a “minute” to get the back of the vehicle cooled down. However, I rarely have back seat passengers, and thankfully, the really hot weather lasts only a few months! I have been very pleased with this car and would recommend it to others. I traded it in a week ago for a larger car only because I need the room for a grandchild, and my elderly parents.

Loved this car
I had my Denali XL for two years and absolutely loved it. It was comfortable, quiet and handled well for a large car. My only complaint was gas mileage. I made two trips to Las Vegas for bowling tournaments with all of my bowling gear and my dad's gear plus our luggage and got it all behind the third row seat. I loved all the bells and whistles, especially the cooled seats in Las Vegas. I'm actually thinking about buying another one now that my frequent trips are over. But it can be difficult to justify the expense of this monster. $80K fully loaded is a lot of money for a family wagon. Even used they're expensive.

Great service they are always prompt on getting service
Great service they are always prompt on getting service done even though General Motors sold John holt a truck that was going to fail shortly after I bought it which I?m not happy at all, I paid for a new 55k truck not a used one I could of have saved money and bought off the lot, not John holts fault the blame General Motors ?
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!
