Tracking down previous owners

[Billy Mild]

My car has had a lot of owners. From what I can tell it is more than the average car. This doesn't bother me that much, but the PO to me gave me the old For Sale ad. It had some mods listed and I would like to confirm they were actually done or what the history of the car is. I found an old insurance card from a PO in the car and tried to Facebook him with 0 success. I bought the car from Iowa, previous to that it was in Illinois.

I'm sure most of the owners on here have a well documented history of their cars, and I would like to get some of that on mine. I keep all receipts even of my previous cars. I was the first person to register my 1599 with the .Net Registry so I doubt any owners have been on this forum.

So, to my question, is it appropriate to try and find the PO's of the car? Is it creepy to contact them out of the blue about their old car?
