I know habbie will fill u in. but i figure i can help.
Xenons and HIDs are the same thing. its the actual headlight bulb thats HID or Xenon. Its just a different kind of bulb that burns brighter.
You can also get ellipsoids and not have HID bulbs, thats what my 318 has. Ellipsoid is a type of bulb housing(tell me if im wrong.) My 330 has ellipsoid bulb housings for the HID/Xenon bulbs.
I have depo in my 318..not as pleased with them as i would have hoped. Pay the extra money for good quality.
We all get the urge...Saturday early morning...nothing to do till noon...
