The significance of this chart can't be understated.
Until people get out of the mindset of thinking they can afford something because they can "afford" the monthly payment instead of calculating the full value of the item then we're just going to go deeper into this mess.
That car sales man won't tell you the total amount you'll be paying at the end of the term, nor will he tell you the interest rate, or amount financed... the only number he will give you is that MONTHLY AMOUNT number.
Never finance with the dealer unless you qualify for those incentives. Always and I mean always have your financing completed prior to even walking into a dealership!
