Hi all, newbie to the forums.. Looking at buying an A4 S-Line to replace my current motor. My budget is around 12k-15k and ideally I don't want anything with over 50k on the clock. Was wondering if anyone on here had any tips (other than the usual kick of the tyre!) on what to look out for when buying a used A4. I've had a go of my mates 1.8 (160) which was fast enough for me however if I can get my hands on a 2.0 (211) I'd be made up. Was also surprised to see that the 2.0 had better fuel economy figures that the 1.8, is it a newer/more efficient engine? Any tips or pearls of wisdom would be greatly appreciated, cheers!!
