I know I am going to catch flack over this post from somebody because where I got the numbers is a mystery to me. I was browsing the many Mustang forums I always do and copied a few lines of text from a post about an email somebody got back from Ford on the production numbers of the 2007 Shelby GT500. It seems like a pretty reliable forum post so we will roll with it.
According to the thread 7828 Shelby GT500 coupes and 2543 GT500 convertibles were built for 2007 plus an additional 6 cars were lost to crash testing and so forth. That brings the grand total of Shelby GT500 production to 10,377.
