I think the question for me would be ---Is there a way to process a pdf to get the info/data in some usable format for database?
I don't have any real experience with pdf or Adobe products that might apply. I'm sure there are other readers who have.
My line of thinking is--Since you have
"I have a Ford site that I can go back approximately 10 years. However, I'm not sure how I would actually get the information from the PDF file to download into the db?"
I would focus on that source for the details you need--unless it is proven/found to be unworkable. My feeling is that you have too many dependent attributes to manually create, maintain and use the database.
It may be worth the purchase of whatever Adobe product allows you to dissect a pdf file, then convert those pieces to be programmatically entered into your proposed system.
