Hi, I'm wanting to purchase my first Audi, in particular the A4 S-Line Estate, I have two option at the moment but any guidance is appreciated. Do I go for a TDI 2.0 (140) 137000 miles or T (190) Quattro with 94000 miles? The first is £5k and the 2nd £4k but does need a new cambelt in the next 5-10k and a service, otherwise in great shape. At this stage which is the best option? I also want to future proof myself, would repairs on both be approximately the same cost if the same thing went wrong?
