What a thread.....
SPF evidently has a warranty that goes with their new vehicles (term applied liberally; forebearance required here, please). They do this, likely because they have confidence in what they create, and want that known. Like any warranty, it covers some aspects of their creation and does so for a specified limit. What's not clear here is just how that limit is defined, start & stop.
Other mfgrs don't offer warranties, for many of the reasons stated in prior posts. Maybe they are afraid of direct product liability; maybe they are afraid of end-user application; maybe they are afraid of......hell, you pick the reason. The simple fact is they don't.
RSimoes angst was SPF's decision, now modified, not to extend their provided warranty to the new owner of this unused car - seemed unjustified to him. Now SPF does also. And I think that says truly positive things about them.
