the only real way to determine orig paint is by a thickness gauge,not by looks..
a few so called survivors have been outed in that manner

before you convince me of that far out factory explanation,
strip some paint away in places
and see how tough the paint strips away and whats underneath it....
i can change a front support out myself
and i bet you would never know it was done unless you were told or you stripped all the paint away...

if it pans out,
that car will be a weird story if it is a factory thing
and it isn't a show/promo car
it doesn't make much sense because if the color was wrong just swap it out with another car on the line?
then cover it all up
