I would get it documented through PHS..... Any Numbers Matching car is more rare than a non-numbers car....but as far as how many of your exact optioned car were built, that's the hard question.
1967 Firebird 400/4spd all numbers matching 1971 Camaro Pro ET Drag Car 1970 Camaro real Z-28 (needs everything) 1963 Impala 409 dual quad 4 spd 2003 Victory Vegas 2009 Pontiac G8 GT (My wife says I have a problem.....)
