2002 v 2003, again
I can tell you that not having the Tip buttons on the steering wheel or a substitute (paddles) is a definite negative step. I really find it rather clumsy to use the Tip stick...it is so much more natural to use the Tip buttons. And if only they would improve the shift speed...(wouldn't have to install a Tip chip and void warranty).
So, much though I hate the notchy shifting Audi manual shifter, I would put more emphasis on it or the multitronic (and of course Audi managed to diminish its attractiveness by delaying its introduction on quattro equipped cars...)when buying another Audi A6. Audi sells more cars with quattro than without in the US. They should have accelerated development in my view. I have read excellent reviews of multitronic.
