Gee, I don’t know about that Dwight.. I’ve seen more than one ‘Avanti Gold’ ‘63 Avanti with Fawn/Elk interior and ‘salt ‘n pepper carpeting… I actually owned one!
As far as EX 2942 goes, If that Avanti indeed became the ‘ Due Cento’ in 1963, there is an issue… since in the ‘Bonneville Record Breaker’ color film, the car is clearly shown with a Fawn/ Black interior!
