Again i thank you for your honest opinion and i do agree with you on most of your technical points but i think there are compromises. With your logic then why get sport exhaust or PASM on an S because it's more of a touring "luxury" Carrera. I agree 100% that the dynamics will most likely change slightly with the addition of a glass roof but not enough for me to not want it deleted and i much prefer the lighter (no pun intended) "airy" cabin. All about what your priorities are imo.The Carrera T is a car that goes to great lengths to reduce weight. They even put lightweight glass. The last gen (991)even revived door handles .Why not make the T a T ? It even costs less than what you are doing . You pay extra (nearly an S ) over a base car to have this along with the choice of manual . Put a sunroof in a Macan . The car itself is a huge practical sacrifice over a sedan or SUV . The seats don't weight much but the roof is not only a weight nightmare , it is positioned right in the center of mass of the car . It ruins the weight distribution. It ruins the torsional rigidity . For what a little sunlight ? You are spending nearly 150K . I am surprised Porsche even offers it . I can understand if you found one on a. lot but you are going to go through the painstaking process of ordering , waiting , wondering , and ultimately spending . Look .. its your money and YOUR car but it makes no sense to me and I told you exactly why. I will, still wish you the best in advance but I can't say its a great move.
As for making the S a Gt3 . It can NEVER happen . I have seen guys try , spend as much as a Gt3 . The only way to own a Gt3 is to buy one . Besides Gt3 does not offer a sunroof .
Btw, never meant to imply you can make an S a GT3. Simply meant making it a sportier S with performance goodies. Thanks for your insight.
