This sounded interesting, knowing that Nissan put in effort to keep their customers happy. Somehow rather, i sense that in reality, things are never ideal. I'm afraid the suggested "campaign" would take a long time before Nissan would consider and to take action abt the rust prob. (BTW, what year is the nissan with rust problem? Has the waranty long expired?)
By the time Nissan really consider a FOC job or partial compensation, this would have probably taken years. Can u bear with such condition on the car?? If the rusty roof left as it is and given the 1 year (assume) waiting time from Nissan, the roof has already bocor and (probably turn into a "convertible"). Not to mention water entry, flooding, spoiling of interior uphostery, incovienience of car use etc......
i don't mean to be discouraging, and I support such action done by Teearts, but I want to remind u that u should prepare for the worst case, or eventualities....
