im in the market for a BRZ/86. i have seen a few 2017 86's go for around 20k. on the other hand i have seen a few BRZ's going for 25k. the BRZ's come with the PP. i was wondering if the 5k price difference would be worth it. i have read a few articles on the PP. i tried looking here too, but if someone could provide some insight it would be greatly appreciated.
