That’s the Glace brothers, in an XK 140 MC FHC (IIRC… heh, sorry couldn’t resist that temptation) in the 2001 Forza Amelia Vintage Rally. Yours truly is in the foreground, enjoying my first ever ride in a 300sl as we depart Amelia Island for St. Augustine.
Somehow Highway 1A1 up the east coast lacks a certain je ne sai quois, of the equivalent routes here on the west coast. Go figure.
