I did not get Xenon on my 2006 325i and regret it everyday. As far as I am told, BMW does not install xenons. I found this site that sells HID (www.ibaptx.com), but worried that I may have warranty issies if I have any problem with the HID (since they require retrofitting). I'd appreciate any comments. Also please let me know if there are places I could get the BMW factory Xenon headlights. Thanks!
