We have had past purchases at the Collinsville store, our sales person was Rachel she is quite the sales person and we are so impressed we drove back to the Collinsille store to purchase our new Canyon AT4X just to deal with her. We live in Bixby which is hour drive but it was worth it. We would also like to thank the other person's that helped make this purchsed a pleasure. Its not often that someone would drive that distance just to deal with the same saleperson but she is worth it. Thanks again Jeff and Lori Parker Bixby Okla.
