Posted about this last week, but MJ's 1991 BMW 850i has been up for auction on Bring a Trailer. The auction just closed, and the car sold for $108,723. ($23!)

Hard to find direct comps given mileage, condition, etc., but from my POV it's pretty clear the MJ provenance played a major role here. Similar cars seem to sell for less than half this number.

Pretty cool collectible for an MJ fan!
