Unbelievable. We here in Ontario have telephones, the internet and yes, even airplanes. Once in awhile we're even given travel permits so that we can visit people and places "on the outside", provided of course that we trust our government enough to detain our families comfortably until we return.
That aside, all this info has been helpful. Didn't break in the 135 gently, in fact it was broken in (with only 450 km's on the odo) at Watkins Glen (yes Kyoshi, had to travel to New York for this but I have friends in high places who helped me in) and its been perfect since. I plan to do the same for the soon to be M3 but I'll pay attention to turb934's advice (and all of the other posts regarding this issue) which generally suggest a common sense "mix" of driving ranges.
