I had a 2003 RSX-S and unfortunately drove it into a cement wall while going about 70 mph. The car held up great, it was totalled of course, but I was fine. I walked away, so I must say the safety on them is awesome. I liked the 2003 so much that I got the 2006 RSX-S for a replacement. Couldn't be happier, I went with Black on Black. Beautiful car. I love everything about it.
The 6 speed manual transmission is by far my favorite part. Nothing compares! Then of course you have the Bose sound system which is in one word, AMAZING. The steering is also a big plus, very tight and responsive.
The only things I would consider is possibly HID Projector headlights, LED tail lights and navigation. Hopefully they will be on the new redesigned 2007, which I will definitely be consdering for the next car!
