Aston Martin DB4
Given a thin data state, this market read for the Aston Martin DB4 has low confidence. Current metrics suggest high undervaluation at 74.96 and a strong speculation opportunity at 76.82, with a 6-month forecast leaning up with a 0.53 probability. Real Disposable Income per Capita is identified as the strongest leading indicator, showing a 0.87 correlation.
What It's Actually Worth
Blended value of a standard 63 yr, 35k mi example, ~$295K 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? 68% 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 85 scored forecasts: 68% got the direction right, median value error ±76%.

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 lower over the next ~12 months (high conviction — 100% of weighted drivers agree), driven mainly by PCE Price Index and U. Michigan Consumer Sentiment.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
