There is a way to get a lower dealer cost of a new vehicle coming off a dealer’s lot, and one of those ways is to purchase a vehicle that has a large profit margin. A vehicle with a large profit margin will be easier for the buyer to negotiate a lower purchase price with the dealer, because the dealer has more room to work with when lowering the price, but still makes a profit on the vehicle. Also, dealers pay interest on loans they use to purchase a vehicle from the manufacturer. Which means that the longer the vehicle is on the lot, the less they make on the sale.
