What it does
The auto-appraiser workflow as a report: selects ~3 like-for-like ACTIVE comparables (configuration-matched via the VIN pattern, mileage-banded within 5% of the subject odometer where possible, with a match % AND an installed-options similarity % per comparable), averages their advertised prices, applies a per-mile mileage adjustment to reach the ACV (advertised-price basis; dealer asks generally exclude add-on and documentation fees), adds the preparer's itemized additions/deductions to reach TOTAL FMV pre-tax, and compares it against the insurance carrier's offer. Ships with a branded, shareable Excel worksheet, and the hosted page lets the preparer re-select comparables interactively (the worksheet and the Excel download follow the selection). Use for total-loss and diminished-value negotiations, client-facing appraisal worksheets, and any case where the preparer needs to certify a value from hand-picked comparables. For a full market valuation with trend, channels, history, and CPO analysis, use the Vehicle Valuation Report instead.
