I'm really enjoying this website, I just purchased a CPO '01 Boxster, are the Litronic Lights the only lighting options for the Boxster? Are there any less expensive options such as xenon? If so, How difficult is it to change the headlights to xenon headlights? Meaning how difficult is it to remove the current headlights and replace them, also does anyone have an idea of what xenon headlights are costing if they are even an option?
