I heard that Porsche has confirmed the name Cayman as the name for the new coupe. It will sit above the Boxster in terms of price, and will initially only be offered in the S version with 280PS.
From the pictures it looks fantastic, and shows another timeless design that won't age. If I lived in a colder climate, I would be seriously tempted, but living in Oz, means that the hood can stay down for most of the year!
