This thread is blasphemy I am pretty sure
If I had to drive through heavy traffic everyday I would buy a TSX or an Accord, not a sports car. Now I will say I have never driven a GTR or the like, but I am an old school kind of guy having only owned manual cars since I was 16 (about 10 years now), and being an enthusiast I feel that a driver should be able to properly drive and connect with a sports car.
Again though, I can not judge as I have never driven a proper dual clutch auto or even an advanced auto like the IS-F and I assume 370Z auto, so I will reserve final judgment (other than to give you guys a hard time).
