I work in finance/lending and this sounds too good to be true. Are we comparing apples to apples here? You say it's only $50 per month for the new truck, but how long are those payments going to last? If your current truck was going to be paid off in 2 years, and you take out a new loan that is going to last 6 or 7 years, you could be paying thousands or even tens of thousands of dollars more for the new truck. I would never recommend buying a vehicle based on a monthly payment. That is an easy way for the dealer to hide the real cost of buying a new truck, which could be a lot more than you think it is.
