Fortunately or not, I "eat what I kill" so I have to pay cash for almost everything in life. Mortgage is only thing to have a note out on since it's the only real tax shelter to take advantage of.
But here is a tip for those who are in a position to pay cash on something:
Find the credit card which pays the highest yield for a reward (either cash back or miles) and ask your dealer if you can break up the payments into 3 or 4 payments so you don't go over your credit limit. Use the credit card, if they'll let you, to make the installments- this can usually be done if you place an order and are waiting for the car to be built/shipped.
Pay off the balance each month until the installments are completed.
At the end you'll have to car paid off, same as cash, and you'll have $500-$1000 in cash back incentive money to spend on extra's or insurance or registration.
Some dealers will not allow you to use a CC because it cost them a couple of % but you can always find on who will.
And some CC's max out at $500 cash back per year.
Good luck!
