Depends on the state... I was able to pay the fee for OK, where the car was originally from, and got lots of titles and registrations. Allowed me to know all owners from 1970-1990... Well worth the $15... Missouri, where I live, however, requires you to be in the business of cars, in other words, owning the vehicle does not allow you to access records, due to privacy laws... If your state allows you access, I say give it a shot. Also, if you know the cars original state, I would try there as well..
I was able to talk to the original owner of the car, he had some great stories and also provided with me some information and leads that allowed me to later find the #'s matching engine and purchase it!
