Looking for an 06ish A4

[EddyP]

HI guys,
I'm after a diesel A4 avant, which is the best forum to find a buying guide or similar on, and look through their classifieds? I've found a few VAG forums like vwaudiforum.co.uk but there don't really seem to be any cars for sale on there so guessing it's not the popular forum for the Audi guys, which should I have a browse through?


Thanks
