The 60 is a truck. A beautiful slow truck. I love the stick shift of the 60 better than the auto of the 62. I have memories of pulling 40mph up I-70 through Colorado, thankful and excited that on a cross country trip I could get 13mph ave on highway after may dad installed a splitter in the transmission. I would love to own a 60 with a V8 installed. No safety features past a strong structure and seatbelts.
The 80 is more powerful, smoother and more refined, but still truck-like. The 93 up have much more power than the 60s, but some still want for more. Much more comfortable than the 60, and
94 / 95 saw the innovations of anti-lock brakes and airbags. These things are also bloody tanks.
Nostalgia and rarity would compel me to drive a 60, more modern comfort would compel me to drive an 80. The 80 is a modern car and a class above the 60 in class and comfort, but that being said, the 60 has an aura that is like no other, in my opinion.
I have an 80 as my DD, but being that I have 3 children want comfort and safety, I could only have a 60 as a second vehicle.
Thats my take. Have fun.
