So, this signature is on the inside of the passenger door (under the trim) of my friend's late 60's Simca Bertone 1200S coupe (one of the 6 rhd converted ones, and in a bit of a sorry state currently, sadly!)..
Where could I start in trying to find out whose signature it is?
No idea what it even says. On my 2005 Mustang, in the transmission tunnel, someone wrote "Hi Ern" which I assume was from one production line worker to another as you have to be understood the car to see it.
