Nick was wonderful.

Reviewed by will64July 15, 2025

Nick was wonderful. I knew what I wanted from the beginning. I called in and Nick answered. Over the course of a few days, he showed me what you had, stayed engaged until i came in to take my truck home. He sent me pictures the three trucks you had, answered all my questions, provided the financing options and deals, and made many a recommendation to get the process done efficiently. I'm grateful it was Nick and not some other guy. His character was perfect for me. I will come in for service because of him. Thanks again! Larry helped out too...

Ramon was the main person who kept me in the loop and provided me with very good customer service so that I could identify an EV. Overall I am happy with the outcome.
