Does anyone know where I might be able to enter the VIN number and find out who were the previous owners. I'm just interested and wanted to know what its original color was.

dont know about finding out about other owners but the vin decoder on www.novaresource.com can tell you a little about the car. To find out the car look on the firewall for the cowl tag that will tell you the color

Are we a 68 Nova, if so the color codes from the cowl tag are:
