Deciphering hte BMW Code

[theBMWenthusiast]

i went yesterday to confirm the car I am getting from BMW, got there, met with my sales rep, and went to the list to see the same kind of car im getting...is there a site where you can get the code how BMW puts it on their inventory list...if you know a site where i can see the code like ZHP and stuff like that i need the code for:
Xenon Lights
Sports Package
Premium Package

i would appreciate the site where u get the code, thanks!
