Great customer service.
Great customer service. Anthony has helped with the purchase of multiple vehicles and always a pleasure to work with. Always an easy process. Will be returning for next new vehicle
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.

I recently bought a 2022 Nissan Rogue SV from Shottenkirk
I recently bought a 2022 Nissan Rogue SV from Shottenkirk Nissan Katy and cannot be more impressed with the outstanding customer service that I received. Zeb Poindexter (Sales Associate) and Marco Compean (General Sales Manager) went out of their way to help my family purchase this car. In my first conversation with Zeb, I told him about my bad experiences with other car dealerships and how it was hard for me to trust a car salesman. Zeb listened to my concerns and asked me to give him a chance, because he cares about the customer and helping them find the right car. I am SO glad that I trusted Zeb, as he was kind throughout the entire process and went above and beyond to help my family get the exact car that we needed. I will recommend Shottenkirk to anyone and everyone. Thank you Zeb, Marco and Donyell Livingston (Finance Manager) for a great experience and making it happen!

I bought my car in for diagnostic review due to an issue
I bought my car in for diagnostic review due to an issue with loud roaring noise when I drove my Buick Verano above 50 miles an hour. Cristina was my service representative and she provided excellent customer service. Cristina smiled when she created me and made me feel comfortable as she listened to me. I felt she appreciated my business and was interested in resolving my car issues. She called and texted me on any developments, as well as returned my calls the same day. I was very pleased with her friendly and competent service.

Great dealership.
Great dealership. Bought a GMC Acadia from this dealership and the sales was assisted by AK Mirabi who was very much customer friendly, customer focused and very much helpful throughout the sales and vehicle handover. His assistance for the sales is truly appreciated. Karime Nava was the finance manager who ran through the finance process and documentation and she was super helpful getting the great deals on the APR and extended warranty packages for a great deal. Truly appreciate her assistance on the finance side. Had a great experience with the Group 1 GMC North dealership during my Acadia purchase
