|4.2 L performance is better than published reviews in real world driving
Nav system controls are not the most intuitive; Lack of B&O stereo
Excellent value -- better choice than S6 for daily driving (quieter, smoother, 18" all season HRs) plus, V-10 on the fender won't help with Sergeant Stadanko at the window. A-6 is still reasonably low pro despite Audi's pimping of the line-up's front-end.
Drive ratio and Sport mode compensate for lack of low end torque off line in 4.2. Well programmed, smoother downshifting (much better than other hi-perf 6 speed autosticks I've driven e.g. AMG).
