I plan on buying a 2007 Civic Si but also looking at other alternatives. I like the RSX type S and SRT-4. Is it better to buy the Si new with full warranty and no miles, or buy a used RSX type or SRT-4, and take the risk of buying a used car. It will be my daily driver, which I plan to rice about. Just intake, exhaust, headers, bodykit, and maybe even a supercharger kit, bolt-on of course.
