My mother used to own an original 1973 VJ 770 series Valiant Charger:
Apologies for the picture, it's the only one mum has of the car unfortunately.
It was a 6cyl worked Hemi 265 with original dragways etc. Well, after mum had major back surgery she moved down to where we are now and couldn't take the car with her, so the car sat at her fathers place and because he didn't care for the car, he let it sit in his paddock rusting away. After many years of fights between them of wanting to get rid of it, her father rang up one day and said "a guy is here, he'll give you $500 for it, I'm doing the deal whether you like it or not, expect a cheque in the mail"
So not a barn find for us, but whoever that was I hope they are restoring the car to it's former glory.
