'08 E90 4,245 miles
I'll pass most of you by the end of the summer.
When I was looking in early $50k was my ceiling. Most of the cars I was looking at were asking 55-ish with lots of options and 15k+ miles, so some of them would probably have ended up below 50 after the negotiations finished up. But I'm happy I got one with 280 miles instead.
Next year I fully expect cars with 30k+ miles to be sub-40k, don't tell my wife.
