To appreciate how rare Shelby Mustangs are you need to see the total production numbers of all Mustangs by year. Take a look at these numbers. The Mustang was a very popular car even in the early years. The Shelby Mustangs are a small fraction of these numbers.
These numbers come from CJ Pony, a great place to find parts for your classic and newer Mustangs. I’ve spent a lot with CJ Pony over the years myself.
