Beer Stein

I bought a "German-style" beer stein at the first reunion auction. The story was, that it was given to Don Yenko, from his daughter, while in Europe for races. She was said to have talked an un-willing Don into a road test demo of his race car and wound up in a slight accident damaging the race car slightly. She felt so badly that, she went shopping for a gift and something that would help her gain forgiveness from Don. It is a very decorative stein and I did get the Cert. of Authen. nearly a year after the auction. My questions are: Does anyone know the truth of this story? When daughter is mentioned, whatis her name? Only child? What year would this have been? I believe that a Corvair was the race car involved? Was Don or the daughter Driving? Anyone know some details? Thanks
