No xenons, or a host of other options.
The best stock C43 I have seen was one for sale by a guy in Kew a few years back, he had a whole stable of classic Mercs, had owned it from new, fully loaded with 70k on clock and had been garaged all its life, and serviced by Raw off of this Forum. Could have come from the Merc Museum.
I think Justin's and Ollies are the best out there, maybe even globally, depending on what you want. Justin's is immaculate, and the Mods look like they where done in the factory, and its just a great car and example of what you can do if you take care and price rather than just chuck the parts catalog at something.
Ollies is just the nastiest, most brutal Brabus eating piece of machinery to come out of the darkest depths of Hampshire, and I doubt you would find a C43 anywhere in the world that would see which ay it went.
I have not come across a better one yet, and I use mine as a daily car
