Two core datasets: vehicle appraisal data (vehicle class, manufacturer, replacement value, age, mileage, engine power, damage type) and historical bid data from salvage platforms (bid amount, platform, accepted bid). This data typically already exists within insurers but is rarely analyzed systematically.

The real work lies in integration: appraisal databases and bid databases are often separate systems with different formats. Merging and cleaning these data silos is a prerequisite for any analysis.
