Methodology

No number without its basis.

Exotic Index starts with comparable observations, adjusts for mileage and confidence, then grades the listing as a deal.

01

Basis

Start with comps.

Every public value carries comp count and confidence.

02

Adjustment

Normalize the listing.

Mileage and confidence move the expected value range.

03

Verdict

Grade the deal, not the car.

Suspiciously cheap becomes Check, not Buy.

Deal ScorePrice vs expected range

The score grades the listing price against the expected value range.

Thin dataNeeds analyst review

Low confidence or fewer than eight comps hides the public numeric score.

Real data postureTransient live listings

Durable depreciation curves require owned or rights-cleared observations.

Exotic Index provides informational buyer-intelligence estimates, not appraisals, investment advice, financial advice, or offers to buy or sell vehicles.
