Generally, there are appraisal agencies in the used car market. But it's best to show the national professional qualification certificate "used car appraiser", and then show the used car appraisal report. Choosing a second-hand car appraisal and evaluation company depends on whether there is a license certificate issued by the Department of Commerce for second-hand car appraisal and evaluation institutions.

Used car evaluation calculation formula:

Overall formula: vehicle evaluation value = replacement cost price × innovation rate × comprehensive adjustment coefficient × market volatility.

1, replacement cost: replacement cost = current market price+various taxes.

2. Innovation rate: the formula for calculating the innovation rate published by the state is: innovation rate =( 1- service life/? Specified service life) × 100%.
