I have made a tool for my client that adds a link to each car to create a pdf of the car details so they can print it out, and hopefully increase sales by the nature of the paper lying around on the desk reminding them about the car and the dealer.
It passes the regnumber to a php file which extracts the info from the database and plots it out neatly on the pdf.
I used http://www.fpdf.org/ as I don't have a PDF library on my web hosting package.
I think this would be a good addition to any future version for others.
