I live in Australia and have a 1997 E320 Avantgarde. I recently viewed a MB promotional E class dvd and it highlighted xenon heasdlamps as one of the differentiating features of the Avantgarde. My Avantgarde has many of the other features mentioned but not the Xenon headlamps. I'm just wondering if anyone knows more about this or if Meredes Benz in Germany has a contact email address specialising in these matters. I have heard that specifications vary from country to country however I'd like to know the facts.
