I am a repeat customer for sales and service.
I am a repeat customer for sales and service. Used the internet this time to purchase my truck and Shawna answered the call. She was very helpful, courteous, answered all my questions and helped me close the deal. Brooke and Julie were great on finalizing the process. Also, dealt with parts and service today, and as usual, exceptional service from both.
