I'm in the who cares category
Same here. I don't worship old racers, musicians and particularly actors !!! Heroes to me are people who save lives - like cops, firemen, paramedics and military personnel.
If you must have a celebrity sign your vehicle, have them sign the underside of the trunk lid !
LOL ... I remember watching a Lamborghini video once and I guess there was a club meeting where the Lambo test driver was a featured guest. People were scrambling to have him sign their car and I was thinking "hell, he drove EVERY car - not just the one's he was signing" !!
