I'm trying to figure out something. Why is the going price for a 70(or similar year) Grande' so low? Research tells me that they were the luxury models back in the day so intuitively I would think they would be closer in price to the standard fastback. Moreover, production numbers tell me that in 1970 39,470 fastbacks were produced and only 13,481 Grande's were produced. Granted they made around 7000 fastback deluxes, but any fastback or Mach I(40,970 were made) is worth a lot more than a Grande'. What gives?
