Personal favorites: A-990 Mopars, '68 Hurst converted Hemi Dart/Cudas, Thunderbolts, ...anything w/ acid dipped / fiberglass front fenders ala the early-mid 60's S/S wars. '87 GNX and the possibility that there were a couple of Stage 2 Buicks that escaped GM's crusher...as well as many others, too numerous to mention.
But..I'm a died in the wool 2nd gen F-body fan and it would be a toss-up between a 73 SD-Formula and for my ultimate "Holy-Grail"...'70-73 Phase III Motion Modded RS Camaro!!!!!
Good Thread,
