I'm sorry if this has been asked ad nauseam but my Googling results in endless threads about older pins and NIB Sterns but can't seem to find the info for unboxed, folded modern Sterns. As if no one buys them this way? Jackpot points for confirming it fits in a 2009 BMW X5 I've seen the Wiki but want to be super sure before I make a 24 hour round trip.
