Gnil, if i may suggest dont forget to order the all wheel steering. I was kind of sceptic but wouldnt want to miss it now, it really works well. And if you like music order the Bose system, dont stick with the normal one. Unlike my S5, where the Audi sound system was great and far superior to the Bose of my 911 turbo, the standard system here is just too weak in the Q7. Not terrible but It lacks punch and definition. 

And if you you take the additional heating (Standheizung) make sure yountick the box of the Emergency Call, because that Is what you will need to be able to steer it via the phone app (very practical when u are out of reach of the remote).

I ordered a second Q7 because the dealer forgot to put in the RSE preparation and now am actually looking at the option to getting another one because i am still not completely happy with the specs - so if u have questions about them just ask, i have done my share of studying them ..:-)
