The s2000 is a better car in my opinion. Lighter, Fast for a 4cyl, Sporty stick shift, Good handling. Compared to the sc which is heavy, gas killing v8. Plus i dont think the sc400 ever came in a manual stick shift. Since your 16 i bet you want a stick shift over a automatic. But if you had the money you can put a 2jz supra twin turbo motor in any one of those two cars. Vids on youtube if your curious. Overall i would say s2000 because its a newer car. Used first generation s2000 will run about 10k-20k. And if you get one please garage it. Because kids steal the s2000 seats and put them in the civics and integras.
