How to Use This Calculator

Enter the Condition #3 (Good) baseline value from a price guide like Old Cars Report or Hagerty.
Select condition class (1 = Concours through 6 = Parts car).
Review the adjusted value for your selected condition class.
Use this as a reference for buying, selling, or insuring — final values depend on marque and regional demand.

How the result changes with Condition #3 baseline value ($)

Condition #3 baseline value ($): The published 'Good' (condition 3) value for your make/model/year. Check Hagerty, Sports Car Market, or Bring a Trailer for comps.
Condition class (1-6): Hagerty condition scale: 1 = museum quality, 3 = clean driver, 6 = parts car.
Matching numbers drivetrain: Original engine, transmission, and rear end matching factory records adds ~25% premium on most collector cars.
Provenance premium (%): Documented race history, celebrity ownership, factory prototype status, or other notable provenance. 0% for ordinary cars, 10-30% for documented special history.
Market trend adjustment (%): Current market heat for this marque/model. Positive = rising market, negative = softening. Check recent auction results vs 12 months prior.

Estimated market value: Projected value based on condition, matching numbers, provenance, and market trend.
Condition multiplier: How your condition class scales relative to condition #3 baseline.
Matching numbers premium: Dollar value added by having the original drivetrain.
Provenance premium: Dollar value added by documented special history.
Agreed insurance value: Recommended agreed-value coverage amount (115% of market value for replacement cost buffer).
Restoration upside to Cond. 2: Potential value gain if the car were restored to Excellent (condition 2) status, before restoration costs.
