People love my '75 Duster and I have no idea why. Everyone seems to have a memory associated with someone who had a Duster. Car people love that it is a slant-6 and tell me to not swap it for a V8 (I won't).
Personally I just like it because they are a rarity in Atlanta. I never see others on the road. It handles terribly (no sway bars), rides like a stoned rhino, and has no working gauges, but somehow I enjoy it.
