Watched the MotorWeek TV spot on the 2004 GTP/WS6 today, and they answered the question on the TAPshift - both paddles function the same - push forward for up, pull backwards for down. That was a very positive review ( but then most of their reviews are ), and functionally the car appears to be great. While some believe that it may look better in a darker color, red, black or green just don't work up here for me - too much work to keep it looking nice. Silver it is!
