I have read about the merc rust problems..I have commented on them ....but until today I never realised the situation was so bad. Today I saw the rustiest "newish" car since my old nissan cherry [circa 1977]..it was a silver E300 Turbodiesel.There was rust on the wheel arches, by the grill, all around the edges of the boot, doors, bonnet..I was gob smacked.The car had a private plate on so it could have been anything from a P reg onwards....
