Ah k yeah that changes things then.
To clarify, in the classic shape, WRX and STI are japanese import only models. Uk only had the UK turbo and P1, all the other specials like series macrae, catalunya etc were just cosmetic upgrades with optional prodrive upgrades, such as the PPP, based on the UK trubo.
P1 was based on a v5 sti Type R with some of the goodies removed (such as dccd) and more sound deadening.
Uk didnt get wrx and sti till the new age shape, 2001 onwards.
