Ok, I have seen several BMW 3 series around town and find that some that have Xenon's are alot more purpule looking than others? Are all the Xenon's that come on the 3 series the same? I have noticed that the M3's are very purple and flicker alot! Also, what is the deal with the pre-facelifted lights? What is the difference and if I have a 2000 323Ci is it pre-facelifted? or not? Please help I am intersted in getting a set and want the ones that are very purple/blue! Thanks
