Chevrolet Corvette C3
The Chevrolet Corvette C3 market currently registers an overvaluation score of 66.98 and low liquidity at 27.87. Forecasts indicate a probable downward direction across 6, 12, and 24-month horizons, with probabilities ranging from 0.54 to 0.56 in a volatile regime. Nonfarm Payrolls (jobs) is a leading indicator, showing a -0.79 correlation with a 9-month lead.
What It's Actually Worth
Blended value of a standard 51 yr, 41k mi example, ~$24.3K 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 154 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 (low conviction — 0% of weighted drivers agree), driven mainly by Nasdaq Composite and M2 Money Supply, though Nasdaq Composite 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.
