I have owned 3 white Holden Astras:
The first one was written off shortly after purchase in 2007, in the Newcastle (NSW) floods.
The second one was written off shortly after purchase when it was T boned in 2011.
I tried going for the hat-trick, but I managed to own the 3rd one for a good 6 months without writing it off.
When I was a kid, my mum owned an old 60's Kingswood wagon with bench seat/column shift. It was the good old days when people still left the keys in the ignition most of the time. When I was about 5 years old I climbed in and started her up. Unfortunately it was in gear so I drove it into the side of the house. I wasn't very popular.
It must be said I don't have much joy with Holdens to be honest.... Although to be fair at around about the same age I filled the fuel tank of my dad's Mk II Jag with water. I thought I was helping lol.
Haha, reminds me. Whilst not a Holden, the parents had a XY Falcon wagon in about 1977-78 (ish). Me and a friend (both about 6 or 7 at the time) were waiting in the car while a parent was in the shop. Car parked on a hill, facing down to the shop door. Little friend let the handbrake off, car was in neutral. Made a new entrance into the shop through the plate glass window. I still live near the shop - it has had concrete (now rubber) curbing installed outside ever since.
