totally disagree with the comments about the xenons. I have them, and they are fantastic, The 2 options i would not be without are Bluetooth - this fantastc, very easy to use and safe too, and you get the bigger display, and the Xenons, they are fantastic, i hardly ever use the main beams, these are my first set, and the output over Standards is phenominal.
My car has most options - 18's, con Pack, Sunroof (a steal at £310!!)IPOD, Winter (comfort), Xenons, BT. but the 2 above are the ones i would pick, The IPOD option is Turbo W**K squared!
Mine is in Luna Grey as well.
