Definition
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 M1 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 BMW M1's pre-accident market value. Comparable sales data shows what similar examples actually sold for, providing objective proof for your claim.
