First post, so please excuse any protocol infractions...

I am about to replace my S4 Avant because it is too small for the growing family and huge amounts of winter sports kit. An afternoon in the Audi dealership was spent being convinced that a Cayenne GTS would be more suitable - and versatile - than an RS6 Avant. I can't see it myself. Drove the Cayenne S and found it a good drive, if of ambivalent interior quality and then compared it to the Q7 4.2 TDi which was fantastic even if not as car-like a drive. Fuel consumption would be best in Q7 but diesel is expensive here in Switzerland and it may not work out so much cheaper in the long run.

Still feel that I would regret not having bought the RS6 though... particularly as I still have not owned an RS4 and now can't for a few years until space is not so critical.
