I was surprised by the success of the Porsche SUV - the Cayenne - which was launched in 2003.
The Porsche Cayenne was not a particularly handsome looking SUV .... and it's interior was not the most practical with a limited cargo area. Yet the Cayenne sold well. (I still can't understand if the badge is what sold the SUV or the actual styling, engine and features).
So it will be interesting to see how the market responds to a 4-door Porsche sedan.
Personally, the whole thrill of a Porsche was the tight, responsive drive characteristic of the selfish 2-door version.
