Go to your Ford dealer. If they are worth a shit, they can get the build sheet and the window sticker. I bought my used 2012 Shelby GT500 at Wickstrom Ford in Barrington, IL and they got both for me. Was way cool because as it turned out, the car actually rolled off the assembly line on my birthday on May 31st of 2011. Was a very cool surprise and now adds cool history to the car for me.
