My wife and I were very impressed with the facilities at Roy Foss. To be quite honest, we had only just begun our search for a new vehicle. We were met with a sales team that truly held our needs above making a quick sale. Alex, our sales associate took time to appreciate our reasons for considering a change of vehicle and proceeded then, to find us the perfect fit. I must also add, that his personal charm enabled to relax right away as he took us through available options. Mike, also helped us to ensure the best financing options ...

My older mom needed a car. The sales person Mohamed took the time to listen and you could tell he really cared. He found us a great car and it was a wonderful experience. After the sale all of the managers come over to say hello, and we were so impressed by the whole Roy Foss experience. I highly recommend you go there to buy your next vehicle. A special Thank-you to Mohamed and all of the great managers at Roy Foss!
