IMHO concerning the looks department the Cayman (GT)S is the winner compared to a 991-911.
If it comes to weight; Cayman; 1 - 911; 0
If it comes to price; same all over
Engine placement; same all over
Engine power; reversed, but that`s the only item
Number of seats? Now, would you be "sitting" in the back of a 911 for your 1 hr drive to the museum? I don`t think so, so lets call it even for both cars.
Anyway; driven E46 M3, E92 M3, now a E82 1M, a Cayman (GT)S could be a possible successor indeed, as said before by Top Gear; what would you possibly want more?
Well, it is more than sufficient for my needs
It`ll do the job just fine.....
