Nope... They did not keep those files. I had an email conversation with the sales manager five years ago and he has nothing from that long ago. Sorry to be the bearer of bad news. I found the contact information on line. They used to have a nice website about their history as a dealership, but I have not looked at it lately.
The Florida DMV was very helpful. They actually helped me get back all the way to the original purchase. The second owner had a little information. Unfortunately, the POP is long gone....
