Xenon and adaptive steering headlights was a separate option on the 08 and 09....it was not part of the premium package (which on my iPhone its hard to tell if this car has edit...based on pictures car does not).
My 09 had xenon from the factory so I cannot suggest how hard the retrofit is. But it has been done...
Xenon like bulb replacement:
If you are in the market for an 07 or 08 the auto transmission should be your primary concern. Read sticky.
Problem was solved in late build months of 2008 and my 01/09 build x3 is rock solid since new and currently at 107k miles it is the most reliable car I have ever owned....this is afterall a fully refined, updated and final e46....
My suggestion....if you find an x3 WITHOUT the tranny issues in the sticky after an extensive test drive BUY it. The HID headlights are far less important than an unsafe transmission. However they are darn nice to have at night on country roads!
