Porsche Cayman........a 911 killer so bad that Porsche won't put the big motor in it. The 911 has got to be the big dog even if it is not anymore. Think of a GT3 motor in a Cayman. Mid engine = better balance.
Very happy car.........one day after the IM-6 build I will own one for sure.
As for the Panamera Porsche scrapped the 4 door idea once in 1963 IMHO they already had a four door in the Cayanne so why build another one? They are selling well though........;-)
