That interior looks correct for a car originally delivered with velour, though I think the colours have faded out from sun. The zebrano console is not correct though - this car originally had black vinyl.
My latest thinking for trusty rusty is black paint, green velour interior. hmm.
I am concerned that I may not be able to do a satisfactory job of metallic (eg Milan) painting at home, so solid colours like black are appealing.
I'm thinking of painting the 280SE soon as a practice run.
