Are they all valuable and equally desirable or is there a model year that stands out for any reason assuming its not a J-code or Boss 351. Not sure if I have read that the Q-code engine in 1973 had less HP than the 71-72 M and Q-codes due to federal regulations and wonder if that's the case, does it make the 1973 model Mach 1 less desirable or since it also was the last of the Classic Mustangs;more valuable. If anyone can shed some light into this will be appreciated.
