Like many things, it depends on what you want. For MB judging, the standard is the way the car left the factory. The high polish is not factory original and would be points off in the concours, most likely on authenticity. The high polish would certainly bring out the "ooh and ah" squad however.
Just curious, but what is the gauge in the bottom right of the polishedeng2.jpg photo?
