Welcome to OzVolvo Matt. This is a great forum. If you decide to join the Volvo Club of Victoria as per Chris’s link above, I am the membership secretary and my details are listed on the membership form that you can download from the club website. A number of club members will be attending the Malmsbury CFA car display this Saturday (13 October) so if you are up for the drive to Malmsbury it is a good way to meet other Volvo enthusiasts and see a lot of other non-Volvo classic cars as well. The event is open to everyone (not just Volvo Club of Vic members so would be good to see some OzVolvo cars there too!)
