4Dr Porches have been around a long time, we just haven't see much of them here in the States.
As far as the new ones, If 4 doors is what you need, (like as in our own Bonnevilles) Why not a Porshe. The lastest offerings like sharp to me.
Whats not to like about this one? I think their engineers did a great job keeping the sleek look and accommodating 4 drs. I think there is a market for it. Business sedans need 4 drs. You can have your cake and eat it too.
