these cars are not given a production date when you order it. each dealer is given a certain allocation of cars at the beginning of each year and the should know the date of production for the car. it doesnt matter when you order your car, it only matters when that allocation for the car you want comes around. some dealers get one m5 car a year others probably get 10 -15 but they all have a list in the managers office the production date of each and every car that they recieve. there is a cut off date for modification
