What the local data says
Warranty break even in Wisconsin
The Wisconsin sample is narrow: Milwaukee is the only mapped metro. Its $161 independent-shop midpoint lands $13 above the median across our 50 metros.
Moving from the independent midpoint to the $212 dealer figure adds $51 per hour. An eight-hour job absorbs roughly $408 of that difference before parts.
Weather moves between about 9 hot days and 123 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.
