It seems like I'm in minority here, but I like small audio buttons on the console.
Isn't the A4 more like Jetta competition than the Passat? My impression from sitting in a A4 was that it's not bigger, not by much in any case, than my Mazda3 (C-segment).
In my opinion, these wagons cannot really be a substitute for the versatility of a compact CUV (RAV4, CRV, Outlander) in both passanger and cargo space. It's true, they are more vesatile than the sedan verisons though. In conclusion, if you don't need the versatility of a CUV, a wagon or a hatch could be a good alternative to a sedan.
