ahhh, the 2 magic words that are key to any insurance or warranty claim.
Also applies to new car warranty.........if you mod a new car and it goes bang, as long as the mod wasn't a contributing factor, you're covered.
Mind you, they'll try and bluff you sometimes like the big 90/10 rort that some rip off insurance companies try to put over you, whereby they state that you're 10% at fault just for being there.......even if you were stationary and legally parked!?
Can't believe some companies still try that crap.......I suppose that while there are still suckers out there that fall for it, they'll continue to do so.
