Are you asking, or is this trivia? I don't recall seeing him bearded, but he did always seem to have a mustache. Do you have any photos?
Well, this picture is from 73: http://f1archive.tomsk.ru/library/fascinationf1/73autgp73-regazzoni.jpg Bye.
I meant to say moustache. Another picture: http://f1archive.tomsk.ru/library/fascinationf1/75autgp75-pace,regazzoni,ecclestone.jpg
but what do you mean by 'Why' ... why do man have beards or moustaches...because they like them, don't they?? So my guess is that Regazzoni liked his moustache. btw I think he still has it...
Well, I've joined a quiz, where this question appears. There are also three possible answers: a. because he lost a bet b. because he liked Sean Connery's beard c. there were problems to use an electric shaver in the usa Perhaps someone knowes.
The correct answer is: d. Because moustache rides are VERY popular with Italian women. HTH IS GARY GREEN BACK ON THIS SITE????????????????????????
