Well, the '71 Hemi 'cuda is my all time fav car. Ever. Of anything. If I hit the lotto and won kabillions that'd be one of the first toy vehicles I'd buy.
The wife's maiden name is Hudson (and we're literally watching Car's with our son as I type this) so we've always been aware of the Hornet and liked it, although the trucks grab my wife's eye more.
As for my personal fav, design wise, aside from the 'cuda it'd have to be an old rum runner.
Cars like these LITERALLY began the need/desire for speed and thus modifications. The lines, the purpose, the urge to modify...everything. I love about any car of this style/era...AND the history behind them.
