Right guys I'm looking to buy an Audi A4 (2010/2011) S line model
but I was hoping for some useful hints and tips on what to look out for..
pro's and cons ..

I hear soo many bad stories about these cars, but I test drove one belonging to a fella who I used to work with..

I'm hoping to go for the 170bhp model but they are scarce in N.Ireland well to buy them within my budget..

If I was to opt for the 143bhp S line model is it safe to upgrade (tune up) and if so which is the best upgrading service,and what is the highest bhp I can bring it up to so its still safe..

I'm only really needing the tuning (upgrade) for torque, not top end speed !!

Any help much appreciated guys
