Car preparation fee is a good way for the dealer to make a quick profit from customers in the range between $500 and $2500. In fact, this fee is not illegal, but it is considered a dealer fraud, because these fees are covered not by the consumer, but by the factory.
Generally, car dealers charge consumers for peeling of plastic off the seats, checking of fluid levels, vacuuming the interior, and washing and waxing the exterior. Most consumers do pay for this because they are not informed that these fees are already paid for and listed on the MSRP. The fraud when you have to pay for something that is already paid for is also known as Double Collecting. This car fraud is very common among car dealers today and you should be very careful not to be a victim of this scam.
