What HID should i use on my 97~98 240SX SE?

[KyoLo]

my friend is selling HID 7000K for $400 and i think it's a good deal, but my other friend told me 6000K looks much better and cooler, more real ...because it projects WHITE light rather than purple ??!!? ...and now i'm confused because my the OTHER friend told me get 11000k so i won't regret for comparing with others who's brighter or so...
If i want 6000K, it would cost me $500 or more, but 7000K would only cost me $400...so now i'm so confused don't know if anyone of you guys have any knowledge about this? because i totally have no idea.......AND i kinda like the original light rather than spending $400 for HID...i don't know what do you guys think?

Hey I would personally go with the purple, but thats mainly cause I see all the BMW's driving around at night in my area and when I drive behind them I can truly see how much a difference HID's are than halogens, compared to the lights just staring you down. I say go with the Purple 7000k. Also I have never herd or seen of a 11000k but maybe im behind on the times of electronics.

just my $.02

im not sure but from wut i was told, the only difference btwn the 4000k, 6000k or 7000k is the color of the emitted light.
