It's been a few days now, and I finally can say my opinion.
I won't use the word uninspired for this design. The design is inspired, but this happened back in 2001 with the B6. The inspiration then ended and Audi were just facelifting the A4 ever since. I'll call this inoffensive.
The A4 being inoffensive doesn't ring any bells for me. The exterior looks like it's 2008 all over again, yet with even less impressive headlights.
The interior is undeniably good, yet nowhere near my taste. I'm very sure tactile quality will be very high, it's just not my cup of tea.
Where the A4 shines is as a package. It's possibly the most complete one in its segment. Good looks, tons of equipment, great engines. But it's even more politically correct than the Passat and that's too much for me.
The C-Class goes for a striking mix of luxury with some sport and definitely lots of freshness, while the 3er maintains this sharp sporty approach that can't be overshadowed, no matter how much beige leather and light wood you use. The A4, well, it's politically correct and therefore, not my cup of tea.
