This is a tale of two 1979 6.9s, both Aussie delivery, both in nice shape.
They are both up at the lloyds auction.
The first is 6132 a 12/79 complianced model:

The second is 6032, also 12/79

Only 100 cars apart and both for sale at the same time.
I would have the blue one, mostly because it seems in slightly better shape and I much prefer the colour.
