That '65 GT is pretty, alright- but speaking personally, I'd give the edge to your sedan. There is a pervasive attitude in "the hobby" that four-doors are on the Earth to function as partscars for coupes and then be crushed, based on some nebulous idea of aesthetic "worth"- an idea I wholeheartedly disagree with. This accompanies a conviction that sixes are to be pulled like rotten teeth and replaced with the biggest V8 possible- again, I can't agree.
All that being said, an Exner car trumps all- so my vote goes to the '60 Chrysler. =P~
