With my comment, I just wanted to add one more anecdotal point :)
I'm aware of the difference between miles and km (though I instinctively tend to minimize it and believe the difference is less than it really is)
I know of that Volkswagen because a million km is headline-grabbing here (on the "anecdotes" section), there are probably cars with a million miles but 1,609,344 km is not a headline-significant number, much like 621,371 miles isn't for the US.
