Well,
As a brand new 116i owner,i was aware of this rust problem on down side of the seats while i was ordering my car to the dealer..
Because in my opinion in case of a major problem,seats can easily be changed or repaired etc..
But when i heard about brown spots on roof i am very annoyed about this situation
This is really un acceptable and rust on the body of car should effect on strenght&safety..
I hope that this would not come real
