Took my car in for front wheel balancing and of course I couldnt help not taking a look behind the wheels of my 2014 e4d.
Of course there is some rust here and there but do your more experienced eyes detect anything that screams attention?

Personally i wouldn' t lose sleep over this, there seems to be no rust on car itself, only shock absorber, other suspension parts and a little bit on subframe. But i can't stop repeating this - once there is rust, it is very expensive and time consuming to get rid of it, so the best and cheapest thing for you to do would be to get a proper undercoating while there is still very little rust. ''Protective covers'' sprayed on rust make things much worse.

@Chigo - compared to a UK car of similar age there is very little rust on that car. Jules

And, in Canada, that a rust free gem!
