I see an add to win a V8 LJ Torana pop up regularly on this site.
I've driven one, several times.
Back in 1973, my local Holden Dealer (Reeves Garage, at McLaren Vale) built two. I believe, City State Motor City built at least one as well.
Two of my close mates were apprentices at Reeves, and did most of the work. The first one built was Orange, and was driven around by the Dealership owner, John Bosworth, then sold to a local Builder. "It will make a nice little runabout for the wife" were his words. He was a Ford fanatic. He took it for a test drive at mid day Saturday, and never brought it back. The second (Red) one was an Order, taken after driving the first one.
The orange car was eventually sold to a young lad who wrote it off. The Red car is still local.
A third car (Purple) was ordered, it was picked up in Adelaide and driven out to Reeves where the boys started to work on it. In the mean time, Reeves received a phone call from GMH. Words to the effect..... If you make another Torana, we will remove your Dealership, so the third car never eventuated. Reeves sold the cars with their own New car Warrantee. The chassis and body stood up well. The Red car was driven to work on dirt roads for probably 10 years. Then sold to a local friend who turned it into a Show car. 350 chev, auto. Sold to someone who crashed it. The second owner bought it back and has restored it to original spec and will never leave the family again.
