I have owned two A3 so far and considering a new car, but I am not sure about the new A3. For some reasons, I am always in a position to get a new car when Audi are doing a restyling, but it's the first time I am not too keen to change.
I find the rear quite ugly (and I note that many people posting pictures of their cars don't show the rear!) but maybe Audi will do a minor restyling quickly, as they like to do.
Also, I find the dashboard a bit strange, particularly the big gap below the temperature control, where there is the cigarette lighter in the middle. I always use my Tomtom Live when travelling (live traffic info) so the pop-up screen would also get in the way of putting the Tomtom in the middle of the windscreen. I would have prefered a screen integrated in the dashboard.
I don't know when manufacturers like Audi are going to have agreements with proper Sat Nav makers!
I am considering keeping my current A3 for a little longer (the car is fine, and looks nice) or maybe moving to a golf, but it seems that we can't get DSG in the UK on a three door golf (probably not to compete with the A3)!!!
