Hi guys so im thinking its time for a change to convert from my slightly modified 2003 Subaru legacy, putting down about 350bhp, to either an 2006/2007 S4 or RS4, obviously Rs4 being my preference. So a few questions i have that will help me with the decision making process: 1. Is there any difference in the saloon vs avant in terms of performance or handling? 2. Servicing costs - How much for your average yearly service? Any really expensive service items such as discs or pads? 3. common issues - Whats is likely to go wrong with these and things to look out for when buying? 4. Is there a huge difference in mpg between s4 and rs4? 5. I have one or two test drives organised over the next few weeks, just curious how comfortable the rs4 is as a daily driver or on long trips? harsh suspension/ cabin noise? Thats all i can think of off the top of my head. Any other tips or advice is welcome.
