I think it's a build time thing with the sline badge on the steering wheel. I've got the 3-door sline and have the badge, but I think the earlier ones (2004 model year?) didn't.
P.S. Regarding the long shutter speed damaging the CCD, from what I've read long shutter speeds are fine, but you can damage the CCD if you're pointing it directly at the sun with a long-ish shutter speed.
