I think mine have looked like that a few yeras ago, the guy had mine before used to polish it like it was the Queens roller (without anybody in the back).
Mind you, he was the operator so had slow days when there wasnt much to do, now its got an owner/operator working it so it has to work and not look pretty.
I like them tho, its a good basic machine, I can fix it when it goes wrong usually, what do they do when a Thermal Wave goes down?
Call a BMW mechanic with a computer to diagnose the problem probably.
