You also need to consider that you really aren't paying 0% interest. they have factored the interest into the price of the car and so they are still making money. Those 0% Financing or $2000 cash back is exactly that! Their is 2000 dollars in interest that you would be paying on that deal instead of paying cash. Is/are their other ways you can buy the truck without financing it? Also, keep in mind that car dealers make most of their money in financing, not the commision of selling the car.That's not necessarily correct. Manufacturers offer this type promo frequently and it has no effect on the sale price of the vehicle. I bought mine through Ford's X-plan for about 2% under invoice. I still bullied the dealer into going into his holdback because there was a similar vehicle at a competing dealer about 15 miles away with more options that I wanted. I got a $5000 rebate from Ford because that was the current promotion. The price of my vehicle wasn't jacked up $5000 to give me the $5000 back as a rebate. Same thing when they offer the financing promos. Now if the dealer is doing it himself, yes, he's paying for it somehow. Doing your research will highlight that.Dealers make most of their money from their service departments BTW.
