My buddy mentioned he knew someone with over 500K kms on his E36, and the same person was told by his brother in law that one of his clients has a 1980's Porsche 911 that just turned over 1 million kms; I believe it's going to be featured in an upcoming edition of Excellence magazine.
Two weeks after I mentioned the above, I was merging on the QEW highway in Oakville and I tucked in behind this slammed Porsche 930; dunno who it was but I suspected it may have been the car I stated above. Then a week later I get an email from Excellence magazine about the latest (April 2012) edition, and it turns out it's the same car! The article shows a picture of 610,524 MILES on the odometer---and the article was written in 2010, so it has more than that now. Mind you, the engine has been done a few times; not bad for a 35-year old, 1-owner car.
