I have seen very few MB that have been modified and actually looked good, MB makes a pretty nice looking car stock. But I think very understated changes could work. I would only do a color change if you get the engine bay, door jams, and wheel wells. It will look like crap if you leave some gold paint somewhere. One thing that might look good is getting rid of some chrome and painting it body color. The most radical thing I would do to a MB is maybe "ghost" flames. If you had say a blown 560SEC that was black and very low those could look very cool.

Going back to old school hot rodders, maybe a W126 with it's top chopped and sitting very low, throw in a blown 502 with a manual trans. It could be cool if done right.
