S4 B8 buyers guide

[robsy]

As per the title I'm looking at getting an S4. I'll probably be going for around a 2011_2012 avant. Can't find any buyers guides anywhere, are there any things I should look out for?
Is there anything that will need doing on a car between 50 to 70 thousand miles?

Thanks
