Biggest Hidden Discounts Available Right Now

These are generally hidden from the public because manufacturers don't want to "cheapen" the car by offering big discounts directly to consumers.

Instead, they give the rebate to the dealer to help them sell the car.

Though dealers can use the cash for many things - TV advertising, tent sales, direct mailings - most of the money is usually given back to customers in the form of price discounts.

Most factory to dealer incentives are used to push slow-selling vehicles, leftover models, or models soon to be discontinued.
