Bought my RSX on presidents day 2005. I have since put 40k miles on it, most of it drag racing at my local track. Its been down the 1/4 mile at least 150-200 times, pulling 1.9 60fts on Drag Radials and it never once complained one bit. It's as solid as the day I bought it, no squeaks, no rattles, no engine or transmission problems. When I'm bored of the track, I take it to the canyons and fall in love with it all over again, hearing that engine sing to me at 8000+ rpms while snicking through that perfect gearbox is heaven. This is absolutely the best car I've ever owned. ZERO PROBLEMS, rock solid reliability!!
Engine/performance, appearance, great sound system, great leather and driving dynamics. Handling is great! 13.6@102mph in the 1/4 with I/H/E/Hondata! Just bolt ons and it responds incredible to modification.
Maybe navigation, HIDs standard. Other than that, I can't think of much to improve on a perfect sports coupe!
