I was surprised to see PUP stay at $3,500 after the power liftgate went standard. So, I cannot convince you one way or another about the value of PUP, but I can run down quickly what's left of PUP--
HEPA filter: Very nice if you suffer from seasonal allergies. Many folks in my area have had it very bad, this Spring, but I've actually noticed a difference. Now, I care very little about biodefense mode. If it ever has real value to me, I've got bigger problems.
Charcoal filters: Nice. I've noticed a difference when passing through certain areas that are reliably stinky (one particular plant, for sure), but I don't know how much real value there is beyond that.
Turning lights: Really not all that great, but better than nothing.
LED Fog lights: Eh. I do want fog lights, though these are nothing too special.
Interior: The leather is very nice, really. The Alcantera stuff is fine. The lighting is . . . something I wouldn't miss.
Lighted door handles: Cool, but that's about it.
Phone dock: Absolutely worthless if you ever want to do anything with your phone while in the car and have the phone plugged in at the same time.
With the liftgate, I checked PUP without hesitation. Without it, I might still do it while holding my nose, but I might not.
