get the 2000 si. If your going to buy a rsx that is a base model your gonna have only about 160 horse at best and thats it the honda si comes with a b16 and that motor is really capable of some serious put out. the rsx sounds unrealistic at 5,000 so there has to be something up with it but my advice would be get the si drop in new e/h/i just to keep it simple and youll have a very fun ride and youll get good performance gas and reliability out of it.
