I was able to track previous owners by going through my states DOT and requesting info based off of the cars VIN. I got photo copies of previous titles of owners that were titled in this state. I think there was a small fee and I had to enclose a self addressed, stamped envolope...it's been a few years back so I'm trying to recall. Car had 8 previous owners. Have thought about trying to contact them to show car after resto and let them know it's still alive but never got around to it.
