Hi Vanessa I am Ronnie's daughter (i.e. Gusto Ronald Coia, Goliardo's son, born in 1942) I just spotted this message. Hmmm not sure about the moustache, I think he grew one once, but didn't keep it for long. He was an accountant for most of his working life but loved cars and used to keep several classic cars in his large garage at home in London so that could be what you are thinking of?
