Anyone have any opinions on the rough (high and low) real world value of a 1970 GTO 455 4 spd numbers matching car - frame off restored with little miles- with air conditioning and build sheets and history. Probably a #2 car - not totally show. Car has 20 options including power seat, window, 8 track, power steering, power brakes, disc brakes. Also, what is the bump in price if the 455's have the air inlet (ram air equivelant) - no value guides address this as a value bump - but see some of those hitting $45,000 and up?? One for sale with the inlet system at Arizona classics for $79,000 - seem crazy high to me. Anyway - more interested in the NON inlet 455 values.
