McQueen certainly was THE 'King of Cool' and helped in creating car/bike fans out of a lot of us Pepsi generation guys...thankfully the Mustang part seemed to get filtered out somehow!?.
Reading online it's interesting that McQueen became a born-again Christian later in life..
'...due to the influence of his third wife Barbara Minty and his flying instructor Sammy Mason, he went through bible studies with the Reverend Billy Graham. It is interesting to note that this conversion happened before he was diagnosed with cancer, meaning it was probably genuine. McQueen's favorite Bible verse was John 3:16 which reads, "For God so loved the world, that he gave his only begotten Son, that whosoever believes in Him shall not perish, but have everlasting life"...'
Here's a link below to a Mustang site w/ a blurb on the original remaining Mustang also it lists the Vins of both it and the destroyed one..
