I leased a Canyon truck.
I leased a Canyon truck. Cameron gave excellent service, he was very friendly and professional. Since this was the first time I leased he made the process easy and understandable. He helped with the trade-in and we did a drive in the truck. His mannerisms are excellent and his dress code smart. I was completely happy with our connection. I shall be doing more business in the future. Thank you, Cameron and GMC!
