yeah, it's weird: it's just got plain old halogens, albeit projector halogens at that.
i have to say, my gf's ML350 also has halogens, but the projector design is really very good. granted, nowhere near as good as xenons, but by FAR the best halogens ever.
i wonder, since the projector housing is -- presumably? -- the same as the xenon housing, if it would be an easy upgrade to xenon?
i'll be checking the mbworld forums
