"Free" is relative. I think it depends on the dealer but I am not 100% sure. I know you are paying for it though....just a matter of whether you get it. I think you get a model of your actual spec, as I understand it. I'll confirm next Spring as I just got a VIN but I'm not 10R yet.
PPAC is a set of mandatory options that you need to chose in your region. For my 12Cilindri configuration, it is for example WIRE, SMRT, TAIG, ACC1, ELEC, SURR and costs 16.6k€. It is a different set for my 296 Speciale (32k€). I don't remember what it was for my 296, but it certainly included Apple Carplay and the Adaptive headlights. For the 296 GTS and the German market, the PPAC included Front and rear parking sensors Apple CarPlay Adaptive headlight system Wireless smartphone charging station
