I am cheating a bit here in that this '66 GT350 wasn't "my" car but 6S101 was the first Shelby I ever saw. That's 17 year old me in its driver's seat in the Francis For Fords showroom in Harrisburg, PA in November of 1965.
I identified the car years later when friend Roger Cackovic, Sr, who was the de facto FFF "performance car manager' at the time, found the original dealer inventory card in his files.
If anyone knows where 6S101 is today, please contact me! It was last reported in the 1974 SOA Registry as being in Canada.
