Picked up my Monterey Red vert with the A6 tanny at NCM on the 27th of Sept. and drove it back to the DC area. I didn't use the paddle shift until the car was broken in, but I use in most of the time now. It is great with the HUD since you can easily see your revs in the tach without looking down. It also shows you what gear you are in. If you try to shift into 6th and are not moving fast enough, it won't allow you to do it and an X shows on the HUD accompanied by a chime. The same is true on downshifting - it won't let you damage the engine with improper shifts. It is very quick to respond when activated. The only problem that I have encountered is when trying to shift or downshift in a turn when your fingers are not on the button, you have to move your hand to a different position on the wheel to access the paddles.
I'm very glad that I got this option on the car
