    The saga continues. Trucks are supposed to be the apple of FORD’s eye. The core is rotten.

    This is down to a supplier not ford!.At least ford picked it up.

  3. crabbymilton

    Yes but the customer doesn’t care who the supplier is so it falls on FORD whether you like it or not.
    If they pick lousy suppliers who’s fault is that?
