Hi everyone. Sorry I write in English but i do not speak German. I am from Croatia and I am looking to buy 2013 S6. Can you tell me something about maintenance, running costs and what to watch when buying? We have bad choice of cars in Croatia so I would import one from Germany. I am planning to put Milltek valvesonic catback with RS6 rear diffuser wit RS6 exhaust tips. Can you recommend me what downpipes and ECU tuning to get? I was looking in APR tuning and downpipes.
Thank you for your help
