I agree with Bakos statement - at the end it is your decision, best you test-drive both versions and decide. Base argumentation here in the forum is:
- PDK and Sport Chrono match up perfectly for best accelaration incl. Launch Control and seemles stressless daily driving
- Manual is supposed to give you THE connection between car and driver ...
The T Concept was introduced in the 911 world as a pure driving and weight concept "lighter everything" no navigation, radio, special lightweight glass etc.
In the 718 world the "T" model tries to do the same, but since you can add most features in the configurator, this is makes it look more like a marketing feature.
Bottom Line: Your car - your choice! - i went with the manual transmission - Good Luck!
