Rear power windows aren't an option (Safety reasons only because for example: If your car sinks underwater the power windows might not work, therefore if you go the the backseats you just roll them down). My brother didn't get sunroof (I guess it kinda makes it look like a sleeper, since the 2004 has 15 extra horsepower than the 2003 and the 2003 doesn't come with a sunroof). He also didn't get the side-airbags (Together they cost $1,000). He got the kicker system with his though, which sounds nice for stock. Just so you know, the break in is at 300 miles, not 3000 (Read the manual). That's about it, if you have any quesiton you can IM me on AIM at speedkrazy602.
