For a car, what scams can be plotted with 0% financing vs rebate?
Here's a number-crunching example of how the "Zero interest rate" offer is misleading. Suppose the offer is that a car "costs $24,000.00 with zero percent financing over 24 months"  or as an alternative, "$3,000.00 off for cash". Ignore the hype:  the quoted prices and the quoted interest rates.  Look at what really happens to two people who take advantage of the two offers, One person hands over $21,000.00 cash, and leaves with the new car. The second promises to make 24 payments of $1000.00, one a month, starting in one month's time, and also leaves with the same make and model new car. The two people have received exactly the same benefit, so the two payment schemes must have the same value. A mortgage program will tell you that paying off a $21,000.00 loan by making 24 monthly payments of $1000.00 requires an interest rate of 1.10% a month, or an effective annual rate of 14.03%.
