I have recently been looking for a 996 4S cabrio or coupe with an x50 power pack, as an option to buying a Mondial. Are the 996's with the x50 that hard to find? I know that not many people would pay the $15k option price for the added power, but didnt realize just how hard to find. I cant be choosy, but no guards red. Any Porsche enthusiasts want to comment on whether the 4S is a better driver than the narrow bodied 40th Anniv 2004 version ? Thanks.
