Great Service
Great experience in Service. Friendly and first class treatment. All of the employees are happy and helpful. Highly recommended for Service, New Cadillacs and Pre-owned luxury vehicles.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Easy and pleasant
We have always found Very professionalFriendly, and honest Sales staff and management here- we have purchased 7 cars here since 1987 Even the porters are friendly and helpful. Service has also been great- no complaints The general sales manager, Jim Edmund, has been at this dealership for Over 35 years and always remembers my name. I highly recommend River Oaks Jeep - it’s a family business and they treat customers like family- The Helfman’s are first class owners. 😎👍

The well coordinated team worked quickly to provide the information necessary so that I could make an informed purchase decision. Representative Kensy was not only knowledgeable but very accommodating. In fact, I was very impressed that she was willing to go into the service area in the high heat in order to lower the vehicle that was on a lift whereby I could look at the interior. Further, her texts and phone calls kept me up-to-date on the progress of the necessary repairs. I noticed the cleanliness of the dealership as well as the positive attitudes of every person I spoke with. Overall, a very pleasant experience. James Simmons Overall, a very pleasant experience. Hey Siri, call Sonya Simmons hey Siri, James Simmons, James Simmons, James Simmons.

I was very undecisive for about 3 weeks but my sales man stuck in there. When I finally made it to Houston he took the time and drove me across town just so I could test a car I thought I liked. And I made that purchase that day within a couple hours
