Curtis Gasper was super nice and easy to deal with and
Curtis Gasper was super nice and easy to deal with and didn?t pressure me. I got the truck I wanted at the price I wanted. Kirk Dominique in Finance was also super nice and did not pressure me to purchase add ons that I didn?t want, and he negotiated well on the ones I did want. It was worth the hour drive.
