I have had a discussion on another forum including rust on our motors....luckily i do not have any sense of rust on the body but just ever so slightly on the front subframe welds viewed from the top of the engine. 06 model so 9yrs old! As this is my first Merc. if i knew more about the later models i would perhaps contemplate a change later. So how do the newer C class models from 2008 onwards fair on rust and i don`t just mean body parts but also components that link other parts together?
