Classic Car Value Calculator

Not exactly -- Hagerty's own published price guide uses a four-point condition scale (Concours, Excellent, Good, Fair). This calculator's six-point scale, which adds "Restorable" and "Parts car" grades below Fair, more closely matches the convention used by guides like Old Cars Report and NADA Classic. It's a widely used framework across the classic-car hobby press generally, so treat "condition class" here as a general hobby-press convention rather than one specific named source's exact grading criteria.

Matching numbers -- meaning the engine, transmission, and rear end all match the vehicle's original factory build records -- genuinely commands a real premium in collector car values because it verifies the drivetrain hasn't been swapped, which matters a great deal to serious collectors. The actual premium varies by marque and model, roughly 15-40% depending on the specific car, so this calculator uses 25% as a reasonable midpoint estimate rather than claiming precision for every make.

Provenance (documented race history, celebrity ownership, factory prototype status) and current market trend (whether a marque's values are currently rising or cooling) are facts about one specific car at one specific moment -- there's no general formula that could derive them, since they depend on real documentation and real-time auction results. This calculator treats them as informed inputs you supply from research (auction house documentation, marque club records, recent comparable sale prices) rather than guessing at a number.

It compares your car's current estimated value at its stated condition against what it would be worth if restored to condition #2 (Excellent), using the same condition multipliers -- but it does NOT subtract the cost of restoration itself. A car showing a large restoration upside might still be a poor restoration candidate if the actual restoration cost would exceed that upside; always compare this figure against a real, itemized restoration cost estimate before deciding whether restoring makes financial sense.

Agreed-value collector car insurance is meant to cover full replacement cost if the car is a total loss, and replacement often costs somewhat more than a straightforward market-value estimate would suggest -- accounting for the time, transaction costs, and difficulty of sourcing a directly comparable replacement vehicle. This calculator applies a 115% buffer over estimated market value as a starting point for that conversation, though your actual agreed insurance value should be negotiated with your insurer based on your specific car and documentation.
