Chevrolet Corvette C4 ZR-1
The market for the Chevrolet Corvette C4 ZR-1 currently shows low appreciation momentum (30.91) and very low liquidity (13.97), with a moderate overvaluation score of 53.38 and depreciation risk at 61.2. Forecasts indicate a slight upward trend over 6, 12, and 24 months, with probabilities ranging from 0.5 to 0.53, though the market is expected to remain volatile; CPI (All Urban Consumers) is the strongest leading indicator, showing a 0.79 correlation with a 10-month lead.
What It's Actually Worth
Blended value of a standard 34 yr, 21k mi example, ~$32.5K 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? 56% 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 54 scored forecasts: 56% got the direction right, median value error ±65%.

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 — 51% of weighted drivers agree), driven mainly by M2 Money Supply and 30-Year Mortgage Rate, though Consumer Discretionary ETF (XLY) 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.
