Salesman was nice but when I got to the back room they took everything out of my pocket. We made an agreement they would take my trade in and no money at all out of pocket. Then they hit me for 2600 after signing all paper work for taxes witch was discussed was in the price. Had issues with the truck agreed upon and they brought me another truck with less options. By the time the truck arrived it was 8pm we got there at 11am and we had a baby with us so my mistake was not looking over the truck but now nothing can be done can t even get the rubber floor mats that was in the other truck.
