Actually it was the 48,669th Kansas City built Ford vehicle assigned a serial number. Numbers assigned when dealer order is received, car built anywhere from 10 days to a month or more later. As far as Mavericks, could have easily been 48,600, 48,700 or any number 1200-1500 higher or lower. At one time KC built Falcon & Country Squire Sta Wgn, those VIN numbers were mixed among the early Mavericks. Falcon gone after '70, the the "woodie LTD"(you know ones with fake wood grain) were no doubt still being built. Comets were built on same line as Maverick, probably 20-25,000 of those came down line before your Maverick. Comet VIN starts at 500,001. Mine wasn't built till June so lots o Mavericks rolled off line before it.
