Chevrolet Corvette C3
The Chevrolet Corvette C3 market currently shows an overvaluation score of 69.42 and a depreciation risk of 59.74, with forecasts indicating a downward trend in a volatile regime across 6, 12, and 24-month horizons, at probabilities of 0.63, 0.65, and 0.7 respectively.

What It's Actually Worth
Blended value of a standard 50 yr, 40k mi example, ~$24.7K now. The green line weighs confirmed auction sales most heavily (the amber dots — what cars actually hammered for), blends in fast-selling "just-missed" listings, and lightly smooths out month-to-month composition noise.
Did our model work? 58% direction calls right
Each faint amber line is a forecast we would have made at that point in the past (12-mo horizon), drawn against what actually happened (blue). Over 153 scored forecasts: 58% got the direction right, median value error ±19%.
Walk-forward: each ghost uses only data available at that date — no hindsight. Data-backed market intelligence, not a guaranteed prediction. Figures are modeled estimates from asking prices, sold comps, and public economic indicators; they can be wrong. Not financial advice.

Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 8 leading indicators (each at its own lead time, de-duplicated so correlated ones don't double-count) into one signal. Leading indicators are collectively signaling higher over the next ~12 months (moderate conviction — 49% of weighted drivers agree), driven mainly by Nasdaq Composite and M2 Money Supply, though Ethereum (USD) points the other way.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
