718s buyers advice for options not included

[chr15x]

Hi All I would appreciate if anyone can help. I have seen a nice 2017 cayamn S with 16000 miles . PDK PASM Sports Chrono sports exhaust . The problem is the things it does not have and I would like to know if its possible to retrofit some items . Its on autotrader for £38950 by BJC and has had a porsche check which was excellent
Wheels are the standard cayman S but in black , No parking sensors , no heated seats and standard lights , mirrors are not folding, not sure if tyres require replacing assume due soon at 16000. steering wheel standard . no headlight cleaning

Thanks Chris
