Buying an RS4

[A4B6Cab]

Have decided the A4 cab is to go, and I am going to get an RS4, having wanted one for years. Can any of you give me a bit of an insight into them? Are they all manual boxes? Ad I cant yet decide between avant or saloon?

Anything in particular to look out for? I'm in no rush so have time to shop around, any pointers or things to watch for will be greatly appreciated guys

Cheers
