hi I'm looking at 2010-2012 Audi S4. What should i look for before buying it?
any problems? any good mods?

You should be looking for one in the best condition, with lowest mileage you can find. CPO would be great, but you can always buy an extended warranty if the car is not CPO'd. I always recommend getting one with a sport differential. IMHO, it is THE option that makes the S$4 special. No real problems. Many feel that the quintessential S4 has Sport dif , B&O radio and Nav. Everything else is gravy. Also you want to know if it is tuned. If so, and the car still has warranty, the Audi dealer will void any warranty if you take it in for service and they hook it up to their computer. This happens from time to time, especially if you buy from an non Audi dealer and there is some remaining factory warranty
