I just bought the new A4 09.. now what are some tips and pointers into making shore i can maintain this beauty of a car.

I bought the Audi Care and extended warranty 7 years 160km I may not of needed it but the piece of mind of knowing I have it, I did.

Also last question installing a system into this car (Subwoofer and AMP) to add some noise would be a good idea?.. I forgot to ask the dealer if the car has a "subwoofer preout" at the back. I didnt get the Ben Ofesun sound system tho anyone know?

Thanks.
