Love how he always says to just put your money in a mutual fund and you'll make 12%. If you used his strategy in 2008, you'd have half as much money to spend on your car as you put into the mutual fund. He also forgets to figure it he depreciation on the used car. They lose value too, just not as fast as a new one.
Love Dave Ramsey's personal finance advice, but don't follow his investment strategies.
