[Poiseuille]

my 2 cents (in bitcoin, of course): age is about right for just off lease, but we find it in a Buick dealer's lot? Any chance BMW didn't want it because they couldn't CPO it? Expensive gamble in my opinion. If I was looking for a used F80, I would use Roundel, and nothing else. Those cars weren't leased and they were most likely owned by fanatics like most of the people on this forum. They will usually come with detailed service records. The bad news: it will probably take longer then you want. But, like I said, it's a lot of money. Regarding the plugs: my brother's '15 F82 was recalled, we assume by BMW, just this week for new plugs at 18,200 miles. He had noticed no issues, but reports that when he got it back it was clearly stronger. He got the old plugs back and they were pristine: light coffee tan and no buildup at all. No explanation from the SA, who is usually pretty forthcoming. No idea if the new plugs are the same as the old ones. Pretty mysterious I think.
