This is a particular favourite clause of theirs I laugh at:
After the problem has been diagnosed (at your cost), the authorised repairer will fax NWC, quoting your Warranty contract number, current odometer reading of the Vehicle, a description of the problem, the repairs required, and the estimated cost of repairs.
NWC will then make a decision about whether to exercise its discretion in your favour or not.
......how very fucking kind of them....
