Back in 2016 I almost had a moment of madness and wanted to order a 718 Boxster through one of the Porsche dealers in the North West. He advised me to not select a lot of extras I wanted, because I wouldn't get any extra money at the end of the PCP for them. So, no to special paint, no to full extended leather in black/crayon, no to 18 way seats, no to sports exhaust etc. 'Keep it simple and think of resale, otherwise you'll get a shock at trade in'.
I'm glad I didn't pursue it actually now. I'd rather buy a used 981 in the right colour with a few nice bits on for sub £30k.
