I just bought a used 2007 IS250 (26K miles), and have fallen in love:loveit:! The car is absolutely beautiful and in exellent condition, black on black, 18" wheels. However, I have noticed that when i'm driving and the sun/moon roof is open there is a really loud wind noise (it also makes a little wind noise when its closed). Am I crazy, or is the noise too loud? Also, there are a few minor paint chips on the front of the car. Can I buy some touch-up paint and fix myself, or should I just break down and take it to the professionals?
