I typically wouldn’t respond to this, but I felt this should be addressed. This review is unequivocally false. I certainly do not scream nor curse out any of our employees. Our entire management staff has been with me for well over 10 years and our sales staff has remained almost entirely intact for my entire 10 years as well, which I am very proud of. That does not happen if the aforementioned actions in this review occurred. Kyle

I have contacted the dealership multiple times and left messages for the service manager to call me back and as of this post I still have not heard from anyone to address this issue.
