What the local data says
Warranty break even in Colorado
The Colorado sample is narrow: Denver is the only mapped metro. Its $169 independent-shop midpoint lands $21 above the median across our 50 metros.
Moving from the independent midpoint to the $223 dealer figure adds $54 per hour. An eight-hour job absorbs roughly $432 of that difference before parts.
Weather moves between about 46 hot days and 156 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.
