I'm gonna guess it will go for around $425,000.
I remember when I was a kid I went with my Dad to a Ford dealership and looked at a '65 (or '66 ?) GT350 in their showroom. Wowsa. It was bare knuckles stripped down ready to race. No carpeting, no headliner, no radio, 5 point race "seatbelt", back seat replaced with an aluminum fuel cell, full roll cage. All I could do was drool.
Then the Ford marketing nerds got hold of it and in following years added creature comforts and weight.
In 2000 Ford built 300 SVT Cobra R’s.
