I assume you mean Porsche by that, won't parts be expensive?
Depends on where you source them. This was a reasonably popular car and while there are still a few thousand of them knocking about in the UK, a lot have been scrapped in recent years, so getting stuff from breakers should be pretty easy + a lot of owners clubs in the UK & Europe - I know it's not an obvious choice like a Defender, but if it were my choice, I'd pick heart over head
