My luck is getting better....
I saw my first 6 series in 1981, and then a few years later read about the first M6. It was slowly building to an obsession, only to be somewhat muted by the bangled E60. Last years release of the new M6 rekindled those memories.
Called my dealer yesterday, he had an allotted M6 not yet in production, it just all worked out, was told end of September/beginning of October I'd have it.
Got an email from dealer this morning (the day after purchase), he tells me that when he marked the car as sold it went into production today, scheduled to be finished August 9th. Depending on shipping/etc. could see it the end of August, early September worst case.
Knock on wood, but feeling pretty good right now!
