What the local data says
Warranty break even in Louisiana
The Louisiana sample is narrow: New Orleans is the only mapped metro. Its $140 independent-shop midpoint lands $8 below the median across our 50 metros.
Moving from the independent midpoint to the $185 dealer figure adds $45 per hour. An eight-hour job absorbs roughly $360 of that difference before parts.
Weather moves between about 85 hot days and 5 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.
