difference between 03-04 type s
 

I'm considering buying a rsx s either 03 or 04. Colors I'm looking at black,silver or milano red i believe its called. So far I know 04 had heated mirrors standard. What's some things to look for when I decide to pursue the S. Also what mileage should timing belt be changed? Any other advice i 'd appreciate that. Another thing . I know the 05-06 different.

Wow, thank you very much for your detailed response. I have to say, I never really considered the prospect of owning an Si because, like most people, I was a bit turned off by the fact that it is still a Civic. That said, I had no idea that the Civic's performance credentials not only matched, but beat the RSX in some important areas. I will definitely keep your advice in mind. Again, thank you!
