I don't know if this is new information or not, but you can get a duplicate factory window sticker for your Taurus directly from Ford for those cars up to 5 years of age or newer.
Unfortunately you can't get stickers for the older ones, but you can get something equally valuable, the original factory invoice. The document shows what the dealer paid, the window sticker retail pricing, options on the car, when it was built, shipped to which dealer etc., etc! This invoice contains all the data you need to have a replica window sticker made for your Taurus.
There is a guy on Ebay offering this service right now, he just needs the invoice information to create it I assume. The window sticker (if yours is available), and the invoice are free from this department at Ford. You need to snail mail to them at first, but be sure to have your email address on the letter. They will respond with that Pdf file for invoices and will also mail the window sticker if need be.
Here is where you write, make sure you have your full mailing address, email address and of course the VIN
number! It will take about 3-4 weeks turnaround time so be patient.
