Oh I love them too... I do like the rounded headlight style of them.
I ‘think’ my Mother-in-law (such a sweetheart...) had a mid 60s Dart or Valiant with the slant 6 and push button trans in it, absolutely Bulletproof.
A good friend in the early 90s had a Dart 4 door with the same 225 engine in it, and last time I saw it then it had nearly 470,000 miles on it, but the car was starting to rust out in the quarters.
