I recently got a 2002 Audi A4 with 88,000 miles on it and I'm not too sure about it's past, other than it had one owner. Right now, I have an extended 2 year warranty on it. My question is, what are problems I should check, and what's the easiest way to fix the fact that all my buttons(window,radio) are white. The car lot also had another one of the same year with 10,00 miles less and 3.0t rather than the 1.8t I have now, is one more reliable than the other?
