“This dealership's service center has a lot of room to grow. I brought my car in for service for a warranty item and the service person denied that what I needed was covered under the warranty. I offered the technical document which demonstrated that it was covered and they refused to read it, stating 'I trust my mechanics opinion over what you have provided me.' I asked to speak to the person managing the service department and he was able to find the document that I had offered to share with the service representative and confirm that my vehicle qualified. Had I not done my own homework I would have been out around $1000.00. I can't say if it was a matter of character or competence, but neither leave me confident in their service.
While in the shop the communication was very poor. I had to initiate communication at every step. My part was delayed by over a week and I would not have known that had I not called them.
I share this so you know what you might expect from this dealership and as a warning to do your own research on warranty items. GM has forums on all of their vehicles, which is where I found the technical guidelines for my warranty item. It is a commonly known malfunction in GM electric vehicles.”

“I just went into GMC castle rock and talked with Brody who in the end helped me buy my first truck!! He gave us the best price possible and we were able to help each other out! His morals and his personality were incredible and he was great to work with during the whole process. He’s a great kid and truly wants to help others get what they want!! I would absolutely recommend to go to Brody!”

“My experience at this dealership was some of the best service I’ve ever had. My husband and I were looking for a very specific used vehicle. Rogan, our amazing salesman, did a great job finding us exactly what we were looking for. After falling in love with the vehicle it was difficult for us to get a monthly payment we were satisfied with. Alyssa did a great job explaining everything to us but we still were not able to make it work. Just when all hope was lost, Tony came in and was able to make a trade with us and get our payments exactly where we needed it to be. We are so happy with our purchase and will be recommending this dealership to our friends. Everyone was very welcoming and friendly! Rogan is the absolute best!!!”

“Had a fantastic experience buying my truck. I worked with Johnathan and he was great to work with. He never pressured me, he answered all my questions, was very knowledgeable, and patient. He wanted and helped me get exactly what I wanted with the best deal. Would buy from them again.”

“I wanted to take a moment to extend my heartfelt gratitude to the entire CASTLEROCK GMC team for the outstanding service and support you provided. I recently had my Audi Q5 serviced to fix the CV joints and front brakes, which I purchased from you on December 6th. The experience has been exceptional, and I truly appreciate all your efforts to ensure my vehicle is in great shape.
Initially, I faced some challenges with the salesman, who was not forthcoming with the necessary information about the vehicle. This led to quite a bit of frustration as I was constantly put off. However, things took a turn for the better when Anthony Banno and Tony Williams stepped in, and then Maurin took the wheel. Luke jumped in and did give me a rear wiper blade, which Jarrod had told me, during his review of service, that it was bad.
A huge thank you to Maurin, Luke, Alex, and Jarrod for taking such good care of me. Your dedication and commitment to resolving the issues with my car have not gone unnoticed. Your teamwork and professionalism have made a significant difference, and I am grateful for all your hard work.
Thanks again for turning this experience around and for providing top-notch service. I look forward to continuing to work with you and will certainly recommend your dealership to others.”
