Many people have noticed that many times there are VIN numbers written underneath the door headliners, on the doors themselves. I've noticed that many of the cars with 15XXX, 16XXX, 17XXX, and 20XXX VIN's have 11XXX numbers written under their headliners. I'm curious, what numbers (if any) appear under the headliners on the 12XXX-series RHD cars? James Espey
