Google, and other search engines can be helpful tools if you are trying to locate the last owner. I would make a copy of the documents before going to motor vehicle, since I will forget that info eventually. Post and google the vin, if there is a known history you may get lucky (or unlucky). Post a photo of the trim tag, get the experts opinions. Download the trim tag decoder from this site. It decodes the information on the tag for you.
Welcome, and good luck!
