I didn't sell mine. When I got the GT40 my wife said, "What are you going to do with the Cobra."
I responded, "Sell it!"
Her response was, "You're not selling the Cobra!!"
I didn't and I'm glad. I kept the 1966 Mustang I bought in "66, too. Likewise, I'm glad I kept it. So many people I talk with who sold their cars, i.e. Cobras, Mustangs and the like, are sorry they did so.
