The threshold is about value, not damage
When the estimated repair cost approaches a set share of the vehicle’s value, the carrier settles rather than repairs. On an older car worth a few thousand dollars, moderate damage reaches that point quickly. People are regularly surprised to be handed a check for a car that still drives.
The valuation is negotiable with evidence
The settlement is based on comparable local sales, and you can challenge it with better comparables, service records or evidence of condition. It is a negotiation more often than people realize, and the first figure is not always the final one.
Keeping the car changes the title
You can usually retain a totaled vehicle, with the salvage value deducted from the settlement, and the title becomes a salvage or restored title afterwards. That affects resale and future insurability, so it is a decision worth making with the full picture.
