Love it. Great when clean and shiny in the sun - looks fantasitc with shiny alloys and red calipers. Also hides dirt and grime very well indeed. Also, for me, goes well with the headlights - you don't notice the line around the edge of the lights so much. Also, for 987 at least, goes well with the side vents and roll hoops.
On the 997 its being replaced by Meteor Grey. I'm sure this is an old Porsche colour - they quite often reinvent the colour schemes and swap special colours into standards - like cobalt which i hear will be a standard price metallic for MY07
