I'll be at the SSC in Eastern Creek on August 15. If you're a NSW Volvo Club member you can contact Syd Neale about a display ticket ($25) at sydneale@hotmail.com
This is probably the biggest annual car show in Sydney, it's a great day you'll see a LOT of cool cars and there'll be a parade lap around the track and you can also usually ride on vintage Sydney buses around the track for a gold coin donation, if memory serves they even have an old double-decker Routemaster.
There's also loads of parts and memorabilia outlets to help lighten your wallets.
