Often, regular cars do not have a huge profit margin for car dealerships. However, this is not the case when it comes to luxury cars. Luxury vehicles enable the car dealership to earn a lot of money. It is therefore up to you the dealer’s invoice price on the luxury car you are thinking about purchasing. Finding out the dealer’s purchasing cost puts you at an advantage and allows you to negotiate for a cheaper deal. However, be sensible and remember that as long as the dealer makes a reasonable profit, your deal will be accepted.
