Hi guys, i'm new to the world of Audi's and after being driven for 8 hours in my brothers RS6, and soon be coming in to some money, i've decided i'm going to look to Audi to replace my old Vectra.

I don't know a great deal about the engines/equipment etc so i'm hoping i can get a few pointers here.

My budget would be up to 10k, i'm looking for an avant, preferably with climate/cruise/leather with some half decent performance. Obviously there is the S4 i could look at, thats self explanetory, what about the other engines/specs in the A4 range, what kind of power do they put out etc?

Any help would be greatly appreciated
