Those 'gurus' should've told you that?
Is it triple-black if it doesn't have a black VT?
Regardless, black interior isn't terribly rare, so it's really just the pairing with black exterior. (as Dick Landy said)
But IMHO, even if it is 1 of 3/4 built, it's not really all that special.
440, or silver/red or some other 'interesting' color combo, would make it more 'special', regardless of how many were built.
This one doesn't really 'pop' with eye appeal - and certainly not with all the flash-rust it has.
