Not an E-type. Ferrari 250 GTO?
Some how, I failed to notice the Prancing Horse sticker.
Apparently, just three were made, to be raced at Le Mans, but they lacked the minimum 100 cars, so just one was raced, as a prototype.
Not completely clear from the text, but this may have been the one that won its class at Le Mans and finished second at Nurburgring.
