Stops quickly well. Driving in DC means I have my fair share of idiotic drivers and Audi brakes have saved me from collisions several times.
Great in snow, ice, bad weather conditions.
zippy, although not as wonderful as when I drove the TT!
Overall I like the styles, though they need to work on interior design. Here again, the TT designers did great on interior, A4 less so but ok. Audi brand reputation and image to me is one of style plus excellent handling.
Like that I can drive an Audi for 6+ years/100k+ miles and still feel safe.
