Hi Was wondering if I could guage opinion from guys who know more about these cars than I... I was until today thinking of getting a B6 S4 with my budget of c£20k. And with that I could get a reasonably tidy 03/53 saloon or avant with c35-60k miles. However I've just checked Trader and noticed you can actually get the B5 RS4 for that money and have seen a couple on there with c50k miles on X Plates? Now assuming they all stack out with service history etc etc, what you you go for? I'm now torn about the RS4 which I'm leaning more towards. They're both the same re insurance. The RS4 is slightly better performing although both amazing. The RS4 allows more options tuning I guess due to have the Bi-Turbos. Fuel consumption on both would be similar although the S4 I guess slightly better. Tyre wear the same? Service costs similar? Any other differences I should know about?? Cheers !!!
