Definition

What is diminished value?

Diminished value is the reduction in a vehicle's market value after it has been damaged and repaired, even if repairs restore it to pre-accident condition. Once a Grand Prix carries an accident history, its resale value decreases, and insurers may owe you compensation for that lost value.

To claim diminished value, you need evidence of your Pontiac Grand Prix's pre-accident market value. Comparable sales data shows what similar examples actually sold for, providing objective proof for your claim.
