The air vents on the 3.6 Carrera are painted in Vulcan Grey, just like the PCM face plate. Only the S gets the free Aluminium air vents.
Btw 69bossnine, I was wondering how well the Vulcan Grey PCM face plate and the silver Adaptative seat backs fit in a terracotta interior. I'm planning to get a 997 Targa 4S next year, but I'm still hesitating between Slate / Black & Terracotta, and Midnight Blue / Black & Sand Beige. I wil be getting the leather vents and rear console upgrades, so the those two parts will pretty much be the only non-leather parts inside.
Does the fact the interior uses different shades of gray bother you, or am I worrying too much about nothing?
(if anyone got a car with adaptative seats and a sand beige interior, I'd like to hear your opinion, too

)
(FYI I prefer to get a black dashboard because of reflections on the windshield, and light seats because seats get real hot real fast with the glass roof - hence the two-tone interior)
