Overall car values declined 0.13%, while truck values fell 0.28%, with trucks experiencing greater downward pressure across several segments. Buyer participation remained strong across both physical and digital lanes, though bidding activity continued to be highly selective and condition sensitive.

Most vehicle appraisals still rely on manual history adjustments, a subjective process that increases risk and reduces profit.

We analyze millions of auction transactions to show exactly what historical events do to the selling price. The result is a VIN-specific value, not a generalized estimate.

A $70,000 truck becomes a $100,000+ vehicle the moment a Shelby, Fox, or Roush package is installed.

But for years, that added value existed in a gray zone, documented on invoices, debated by lenders, and inconsistently recognized in the secondary market.

The problem was never the value. It was the lack of a shared language to prove it.

That's changing.

Black Book now integrates upfitter package data directly into vehicle valuations, at the VIN level where possible. When a lender books a vehicle, the upfit value is already recognized. When a dealer prices inventory, the guesswork is gone. When an upfitter delivers a build, its worth is validated by a trusted third party.

Dealers, lenders, and upfitters have always been part of the same ecosystem. Now they're speaking the same language.

Learn how upfitted vehicle valuation is evolving and how Black Book helps dealers, lenders, and upfitters confidently price and finance modified vehicles.

Managing a vehicle portfolio at scale means one thing: you can't afford to be wrong on value.

That's what ValuEngine is built for.

Black Book's ValuEngine gives lenders and OEMs a self-service way to run batch portfolio valuations on demand, the same analytically-driven data powering our API, without the integration overhead.
