Mark, I also have a silver 2000 Boxster S with all the options available. I can tell everyone that I will never in my life own a vehicle without Xenon HID lights. I may be biassed since I import xenon lights for a living but it's still a fact.
Anyways, please don't go ruin a beautiful car by adding a rear spoiler and making it "ricey" looking. Let a nice car stay nice and enjoy it for what it is.
