Mustang is very nice, it wouldve been tough for me to loose that Cobra (kit?) .... I know which one that get the most attention,,, and its beautiful Blue with White Stripes. 
The AC Cobra in the photo below is not the actual car he sold to get the Mustang. It WAS blue w/white stripes. It was a 427 S/C and went like he**. It was one of the modern manufacture Shelby Cobras from the VIN's Carol had left over from original production run in 60's. These were known as "Continuation Cars". Manufactured at Carroll's facility and signed by him as well.
Quote from Wiki page on AC Cobra: (
http://en.wikipedia.org/wiki/AC_Cobra)
"From the late 1980s onwards, Carroll Shelby (Shelby Automobiles, Inc.) and associated companies have built what are known in the hobby as "Continuation Cars"; Shelby authorized continuations of the original AC-bodied Shelby Cobra series. Produced in Las Vegas, Nevada, these cars retain the general style and appearance of their original 1960s ancestors, but are fitted with modern amenities. Initially the car everyone wanted in a Continuation was a 427 S/C model which was represented in the CSX4000 series. This was meant to continue where the last 427 S/C production left off, at approximately serial number CSX3560 in the 1960s."
