If the laws dictate that they must repurchase the vehicle, they HAVE to repurchase it. It has nothing to do with willingness on their part and the Corporate side of MB is completely removed and separate from dealer franchises.

@Surge Yes, it is an issue with the engine as a whole. When i went to turn in my car they had two brand new S63s that had the same pattern of issues as my car had.
