Mazda 6 Kombi vs. e.g. Passat?

Hi Folks, I’m currently in the search phase, which car I should buy. There are Audi A6s, Passat Variant, RAV4 2006, Avensis Combi or just a Mazda 6 combi. The A6 disturbs me the price/performance ratio and the service behavior. The passat is bad for both the price and the cockpit, but technically absolutely ok. RAV4 2006 likes quite well as the Avensis (but only after Facelift 2006). I was very surprised by the qualitative impression of Mazda 6. H but so far neither test drives nor the big Navi can test, which is very important for me. In the press there are always very different statements about this. What is your opinion about the new 6? Can it be compared with the other ones at all? Do you always have the feeling that the German Motor Press very rarely makes a comparison to the Mazda 6. DEr is always tested alone. Does someone have the current DVD Navi and can say what about the quality? Thank you
