Caught up with fellow Perth 6.9 Owner yesterday - 2 735G Astral Silver 1979 6.9's! Will arrange a Drive / BBQ in late September for any Perth, WA 6.9 Owners (details will follow but contact me if you are interested). We are aware of about 10 in Perth so hope to have at least half of those there!
That sounds like a great idea and would attend if I was closer than on the opposite side of the country (and if I had a 6.9) :)
I would like to do something similar in Sydney but hope to do it with the local Mercedes-Benz Club of NSW. Time to get some plans together and see what the club has planned too.
