Hi guys i'm looking for advice please as i'm thinking of buyng a RS4 2006/07 sort of area. I'm currently driving a BMW 2001 e39 M5 and would like something newer. I had a S2 many years ago and loved it. I have always liked the RS4 shape (saloon). 1. What should I be looking for. 2. Is there any common faults (I'm not sure if the RS4 suffers from the same problem as RS6 in suspension leaking) Advice please guys as I'm swithering but I also don't want to be throughing loads of money at it also. My car has only got 73k on it and runs like a dream and I've had very little problems with it (touch wood) What kind of running cost for it and what's the service interval etc etc. What sort of cost should I be looking at for this sort of age? Thanks and look forward to replys. No BMW jokes please!
