So I went without the PUP, and the self-presenting door is the only feature we are sorely missing. It would satisfy the desire for me if the fob had a button to open the front doors, too.
Of all the PUP features, this is the one we miss the most. So, in retrospect, it wasn't worth it because that feature alone wasn't worth $5k for us.
It's been pretty cold lately, and I haven't been missing any of the sub-zero features. The stock sound system is pretty good on it's own, and the HEPA filter is not something I have been yearning for like self-presenting doors.
Hope that helps some others.
