How are damages measured when a car is damaged but repairable?
The default legal measure is the drop in market value immediately before versus after the accident, with repair costs admissible as evidence of that drop. Many states allow reasonable repair cost plus any remaining loss in value, but capped so recovery never exceeds the pre-loss value or, in states like Maryland, the spread between pre-accident value and salvage.
Is the 17c diminished value formula binding on a car damage claim?
No state uniformly requires it. The insurer-favored 17c approach caps base loss at 10 percent of NADA retail value and then applies damage and mileage multipliers, and commentators have called any one-size-fits-all formula inaccurate. Market-based comparables and an independent appraisal can support a larger, better-evidenced figure.
Can a repair invoice alone prove a vehicle damage claim?
No. Courts cap recovery where repair cost plus residual loss exceeds the vehicle's pre-loss value, so the claim needs market evidence: the accident report, complete repair estimates, before-and-after photos, KBB or NADA market reports, and ideally an independent appraisal assembled into a single documented demand package.
Can every owner recover diminished value from their own insurer?
No; rights vary sharply by state. Some jurisdictions limit diminished value to third-party liability claims, others require express policy coverage, and several have no statutory formula at all, leaving outcomes to case law and contract terms. We frame each diminished value appraisal around the measure the governing state actually recognizes.
