What’s the attraction?

I would drive the wheels off that!

When you think about the mid 60s what are some of the best looking cars? Corvette, 64/5 Chevelle, I think Mopar hit on a good one with the 66/7 Dodge Coronet and Plymouth Sattelite, 64 Galaxie? Although I think the 63 galaxie is a better looking car than the 64 but still, the styling didnt start hitting home for all makes untill 66- up IMO.
My 65 Sport Fury is my favorite all time. Just pure sex on wheels IMO. The 64 Fury is pretty nice as well. Then all the 65-67 B body cars and in particular the Plymouths. Add in some other brands the 64-67 Fairlanes, 65 Buick Wildcat and Riveria, 66-67 Old Cutlass/442, 66 Mercury Monterey and Marauder. etc, etc.

You can tell I have a thing for mid 60's cars and especially big boxy ones. Some may think they're ugly but not me!
