In researching this order type, I came across a reference of a Summer-Winter Rental on a Marti Report with Romy Hammes as the selling dealer. Romy Hammes was one of the dealership to hold both a FALS (Ford Authorized Leasing System) and FRCS (Ford Rent-A-Car System) franchise. See attached ad. I believed that the Summer-Winter Rental order type defines a vehicle destined for one of these programs. Also found a reference that this order type is code N.
I'm assuming the difference between a leased car and a rented car would be the length of the term, but there may be other differences as well. Anyone know more about these programs?
