1968 was the year when suddenly everyone loved green. Also the GM a-bodies were restyled and you would see many green LeManses, and Chargers, Polaras, Mustangs and Cougars too. Then for the next five years, about all you saw was green, and to this day people groan about green Mopars. But I would have to go with Medium Green Poly, because to me, green is the iconic 1968 color.
