I've looked at the Euros on Ebay, also, and I am not sure if they are totally Euro. They look no different from the semi-Euros that I have on right now(1994 E420). The true Euro headlights should look like the ones on the site listed below. I would research the ones on ebay right now (sold by mercedes991) if you are thinking about getting them.
