This may have been asked and answered already but I am new to the Porsche family. What are the pro's and con's of the Carrera S and 4S? I know this is the 2wd and 4wd versions. I understand four wheels that are stuck and driving to the pavement are better than two with traction and all but is really a big deal? I ran across a 2017 Carrera S that has a price tag of $88k with 4k miles. I was holding out for a 4S but not sure I can pass this one up. Also, can the 420hp S or 4S be tuned for extra horsepower? Thoughts and recommendations? Thank you.

 

Sorry, probably should have put this in the 991 section but any help would still be appreciated.
