All post-1980 build Panteras were hand built to order; the reformed company after Ford departed apparently did not build many on 'speculation'. So some Panteras likely took longer than others depending on what a customer spec'ed or the availability of parts, now being bought in much smaller quantity. I've given up trying to apply any sort of logic to DeTomaso build-dates vs serial numbers- even during the so-called 'Ford Era'. Too many things went on for any generalizations.
