I saw one in the metal last week. Very nice looking. However, I share the observation that the exterior beauty of the Audi in general tends to age quickly whereas the Porsche, regardless of the model just keeps looking better and better. I dont think the S5 could be considered as a substitute for thr CS. After driving a Boxter, I think you would be dissapointed after the new wears off. I use my CS as a daily driver as a inside/outside salesman. It works very well. With the backseat in the S5 being pretty much useless, the CS also gets the nod for storage/ultilty value. Do yourself a favor and buy the CS.
