Fiancee just bought an '07 X3, with Beige and Black two-tone interior; Premium Package and Premium sound with 47K miles. Took it to BMW dealer to get it checked out and all it need was a new battery, a bulb and a wheel alignment. Wanted to know if there where any common issues that might be coming down the pike, as it is about to come off warranty.

Also, the "si" of the "3.0si" is missing off one side. Where can I get it and what should I use to stick it back on?
