Since starting this thread nearly 2 months ago, my search for a 60 series stepped up.
I found the perfect car, owned by an old couple for 25 years, always garaged (500km from the coast), never been off road etc etc.
I drove it home over 700km and quickly gave it a detail. There's not a pin hole of rust and it's been maintained well. Best of all it's not modified.
In Australia, these have a hard life and it's almost impossible to find one without a lift kit, big wheels, big front bar and rust.
I love it!!
