I wouldnt take too much of a delay. It is pretty cool, but it pales compared with say the 1 day M School. Since I think all M owners should do the M school, the value of PCD is limited.
The agenda is roughly 1 hour of driving basics/safety training. 30 minutes of track time (with other PCD customers so traffic can be slow with all the SUVs, and you aren't allowed to pass). 30 minutes on the offroad track with SUVs. 1 hour factory tour. 45 minutes car delivery walkthrough.
The track time is the best bit if you already did ED and have had the walkthrough and factory tour.
I took my Dad last time and he loved it. For me, having done a decent amount of track driving, and having done the factory tour before, it was not so special.
