Salesman was very nice and helpful.
Salesman was very nice and helpful. But, the figure he gave us over the phone was different once we arrived at dealer. There were several extra warranties added. But we were able to negotiate and get those removed. The main issue we have is with the trade in evaluator on their web sight. The evaluation showed an estimate of $5,500.00. We were very honest about the truck, which was in good shape for the age of the vehicle and had many extras added on to it. When receiving the breakdown at the dealer they offer us only $2,000.00. This was very insulting, we know that was an estimate but they came no where near what the vehicle was worth. Thus having to make a decision to leave without making the purchase or continue negotiate which we did and ended up paying more than we planned on doing.
