As the title says, I'm looking to change in the near future to something more modern (current car is a 2004) and so far the A4 Avant is winning. It's FWD, manual and economical, which is what I want. However, the B8 started in 2008 did't it, so how old is too old in terms of spec? I could probably afford to go for about a 2010/11/12, depending on trim. Ideally I'd like S Line (I won't go back to cloth seats), and is there anything different in terms of the infotainment system that I should be aware of between the years? I'm just looking for something as modern as possible, but also don't want to get a 2012 necessarily, if a cheaper 2010 is identical.
Thanks in advance
