I'd have to go with the black or t-red E1 SVT as the best looking, with the black '99 SE a close second. I had my choice between a white 2000 SE Sport or a Red of the same trim. I went with the white (should've got the red... it had a moonroof... doh!)
I just wish the SE had a more solid looking front bumper, like the SVT or the new Mazda 6. I don't like the 'curved in' look that ours have.
