I must tell you that I think the '99-'01 headlights are sleeker and look better with the smaller non "S" or turbo air dam. Yeah I know the boxter has them but it's the truth. I bought a metallic black '01 loaded(very loaded) C4 with full leather and PCM and 11k. Wow. 60k bought this car and I personally would rather have a loaded '01 than a stripped or average '02 in a off color. I have driven a '03 and mine. The difference in hp and diplacement is not a big deal and I did not notice the difference at all.
