They have to assign them buy the order of which they're built. There have been posts that state dealers have 2 cars in D1 status and people didnt get their car assigned to them until much later than 12/3. It doesn't take a rocket scientist to figure that out. They are definetely not building them per vin# assignement or sequence- that has been proven by post. It does appear color may have a factor in badge numbers but not totally proven yet. Doge will build the challenger late April for May Premier you can find this on Dodge web page. Then do the math how many will they build a day 120-150 is my guess divide by 6400 or is it 6900 to include 500 for Canada. The writing is on the wall just have to read it.
