Ehhhhhhhhh, indifferent. Porsche does nothing for me. I much prefered the older Cockster, the model before, I'd go for the R if it were me.
I'm sure it's a wonderful drivers car, not that I would ever be allowed a test drive in one, however they are almost so well engineered it becomes boring.
But in terms of a car to drive fast, I'm sure it's wonderful and the owner will have a lovely time!
