Great customer service.
Great customer service. All of my questions were answered in a timely manner. I was kept updated on my vehicles repairs daily. My vehicle was returned to me cleaner than it was when I dropped it off. I would definitely use them again.
This truck has a jerk when changing gears sometimes.

Overall good dealership.
Overall good dealership. Had an initial issue with a brand new truck that eventually got resolved, however in order to do so I had to involve the GM. Service dept is pretty good, but I don’t understand why they don’t wash your car every time?? They literally have their own automated car wash and porters, but don’t make this a normal part of doing business. This is one of the little (easy) things that helps differentiate service at higher end dealerships.

I highly recommend this dealership to anyone considering
I highly recommend this dealership to anyone considering buying a vehicle. I live in Colorado and found one of their vehicles online. When I called, William picked up the phone and gave me honest answers to every concern I had. Soon after, I was contacted by the Sales Manager, Jason, who made me feel even more confident about the process. They picked me up from the airport, and everything — absolutely everything — was exactly as promised. From start to finish, this was hands down the best car-buying experience I’ve ever had. These guys are true professionals. If they give you their word, you can trust they’ll stand by it. Going forward, this will be the first dealership I check when shopping for any future vehicles — especially high-end ones — because I know I’m dealing with a team that values honesty and integrity above all. Thank you again for an outstanding experience!

Brandon was absolutely wonderful throughout the entire
Brandon was absolutely wonderful throughout the entire buying process. He greeted me in the parking lot, full of excitement && he offered me a warm welcome and assured me that he would take care of my every need. Brandon’s initial impression is how I went from just browsing that day, to buying. I was a bit weary of repurchasing here again due to the customer service I experienced previously which greatly lacked excitement, attentiveness, and clarification. I can honestly say Brandon excelled my expectations, he even went above and beyond them. Brandon has also randomly called to check on me && to assure I am still 100% satisfied with my ZR2 throughout the months following my purchase. Brandon made sure I got exactly what I was looking for, as well as making sure I received any and all incentives I may have qualified for. Derrick in financing was also amazing throughout the buying process. Derrick answered all of my questions && made me feel very comfortable and welcomed as a customer, something I also didn’t experience previously, even throughout the financing part. He worked very hard to get me the best rates possible, and he did exactly that. I have purchased 2 ZR2 Silverados from this dealership. Because of Brandon’s && Derrick’s’ AMAZING customer service, I will be returning for all future purchases. I will also recommend my loved ones here. I left feeling very appreciated and valued as a customer. Brandon and Derrick also worked wonderful as a team together, displaying strong communication skills and ensuring my every wish was met. I highly recommend this powerful duo to anyone interested in buying. Rick Hendrick Chevrolet, I’ve had my share of new purchases in my day, Brandon and Derrick and exhibit the type of respectful && kind customer service that you don’t find every day. Cherish them. They’re a blessing to any company && any customer they help. They completely reshaped my view and experience with your dealership. I’m happy to be a customer.
