best place for A4s online?

[maix27]

Hi folks,

I'm looking at an A4 as my next car. (currently have an A3).

I'm after a 2.6/2.8 V6 Quattro, but i'm having trouble tracking a decent one down.

I only really use PH, what's the best 'audi only' forum for the UK market with a decent clasifieds section?

Any pointers much appreciated!

Also, anyone got one? What are they like?!
