What the local data says
Warranty break even in Nevada
The Nevada sample is narrow: Las Vegas is the only mapped metro. Its $143 independent-shop midpoint lands $4 below the median across our 50 metros.
Moving from the independent midpoint to the $189 dealer figure adds $46 per hour. An eight-hour job absorbs roughly $368 of that difference before parts.
Weather moves between about 137 hot days and 10 freezing days in the mapped metros. I would use those figures to frame contract questions, never to assign a breakdown probability.
Local prices belong beside the contract's labor allowance. Giving the plan credit for the entire invoice before checking that allowance makes the warranty look better than the paperwork supports.
