That makes sense about the interior code sequence. Mine is a standard black #208 and the tag in question is a deluxe black #218.
Jim, yours is # LOR516525, standard int. built 11D. Mine is # LOR500278, standard int. built 11C. Seem like a high number (16247) of cars to be built in a week’s time.
Vikki, what were the codes on the car you documented. And as I recall your VIN was not to far off from my convertibles.
