It was an absolute pleasure working with Jack and Douglas during the recent purchase of my Chevrolet Silverado 2500 work truck. When I first called to inquire about the vehicle, Jack provided me with stra during the recent purchase of my Chevrolet Silverado 2500 work truck. When I first called to inquire about the vehicle, Jack provided me with straightforward and transparent information—no sales pressure, no exaggerated claims. He genuinely focused on helping me determine whether the truck would be a good fit for my company’s needs. He also went above and beyond by assisting me in finding an insurance carrier willing to insure a commercial vehicle, since my existing provider, State Farm, could not. Douglas provided outstanding service throughout the purchasing process. He took his time explaining the truck’s features and demonstrating how the utility bed operates. When I requested additional options such as a bed liner, he promptly arranged to have them completed. Douglas also guided us through the financing process, helping us secure an excellent discount and a very favorable interest rate. The entire experience at Sierra Chevrolet was professional, transparent, and stress-free. Both Jack and Douglas demonstrated integrity, knowledge, and genuine care for their customers. I look forward to returning to Sierra Chevrolet in the future for any additional contractor vehicle purchases. Thank you, Jack and Douglas, for your professionalism and dedication. More

They had even assisted me with finding an insurance provider who was willing to provide insurance coverage for my contractor work truck. I wasn't able to obtain an auto-insurance policy through State Farm, because State Farm does not insure commercial policies anymore. More
