OK, so it sounds like there really isn't a whole lot of reasoning to the VIN and BDY #'s regardless of the dealer. I just keep hearing people talk about a "known" grouping of COPO's and finding several cars(at least 3) with very close VIN's(less than 31 apart) and built the same week yet it does not make for a "known" grouping. What actually constitutes a "known" grouping? If there were 50 BE axles that showed up at the same time and orders were released for those 50 COPO's, did those cars share BDY numbers sequentially or just close to each other? I see cars built in June with a VIN higher than a car built in May with a lower VIN, but the June car has a lower BDY number.
