Just bought a MY2013 C207 from a main dealer, it's done a tadge over 20k miles. When I viewed it on Saturday there was a 'Service due' indicator showing 180 days before the next. The salesman reckoned at the time that the service wouldn't be part of the sale as it was a way off, fair enough. Picked the car up on Wednesday and he mentioned that the service had now been done by them, and sure enough the service indicator has been reset and now shows a year before the next one is due. He also said they'd done the paint protection as well. Excellent so far. Being a slightly suspicious bod I checked the oil when I got home. It wasn't clear at all, quite dirty. I've flagged up my concern with the salesman and await a response, but is there anything else I can look at in the interim?
