Very nice! Congrats. My wifes next car is the Q7 TDI S-line. Welcome to the club of "Wow.. these Germans really know how to build a car that can tow big loads with amazing ease and stability... and it doesn't have to be the size of Texas!" ... there were designed to do it!! Just wait till you hook up the boat and the parking distance control ont eh nav screen shows you a trailer behind the car
.. it switches to "Tow Mode" and everything on the car adjust for towing. My V10 Touareg is basically the same car.. same air susp, etc... and i can honestly say it tows better than my Armada did.
Congrats.. and welcome to the club.. you are going to love it!
