About as much difference as there is a 73 Super Beetle and a New Beetle.
Difference are (but not limited to)
- Frame materials
- Seat tube angle
- Head tube angle
- Fork Rake
- Fork length (made for 27" vs 700c wheels) which affects brake arm reach
- Seat tube diameter
- Head tube diameter
- Bottom Bracket shell (diameter, press fit, English/French threaded)
- Compact vs Standard (old) geometry
- The frame's "road worthiness". Basically, is it rusted out or pristine.
...and that's just the frame. The components have difference, too.
