My experience with Castlerock Chevrolet since 2020 one of
My experience with Castlerock Chevrolet since 2020 one of the best. I appreciate their customer satisfaction. Puts their customers first. My car engine almost destroyed by an oil change of a place I used to get by cheaper but no more. Thank u again.
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.

Was looking for a 2025 GMC Acadia Denali.
Was looking for a 2025 GMC Acadia Denali. Went to AutoNation and was met by Caden Noar. He was fantastic! Showed us the Acadia he had on the lot, gave us a test ride and answered all our questions. Not once, did he pressure us to buy but was more interested in answering our questions. After the test drive, we noticed a Buick Enclave Avenir in the lot as we were exiting the dealership. Liked the car looks and went back into the dealership to see if Caden was available to show us the car. We knew nothing about the car. He came out, gave us a test drive, answered our questions and then asked us if we would like to see another feature of the car, so out we went for another drive. Again, no pressure to buy and we parted. Over the weekend, we decided we really loved the car and called Caden on Monday to see if we could discuss the price and terms. Bottom line, we bought the car at the price we wanted. Outstanding service from Caden to the Sales Manager to the Contract/Finance Team!
