Oh but Andy - the real fun begins when you try to match a number for 3 series - NARRC/NERRC and NEDIV nationals and NYSRRC. Truely awe inspiring! Or better - I would like the number I had last year - signed John. No last name or any hint as to car/class. When you are doing the 20th one of the day you get bleary eyed and see the car year as a number request!
