Oh yeah they were cool.
Very BMW-like rear suspension.
I had a 2 door 610 that had a similar rear end.
And I would kill for a '79 2 door 810 with a 5 speed transmission (almost impossible to find these days).
Early Skyliners were built from a similar platform.
My first car was a '73 Datsun 610. Totally fun car to drive.
