Dodge Viper SR I (1992-1995)
Showing appreciation momentum: sale prices +3.4%/mo, and +43% vs 12-mo avg.
What It's Actually Worth
Blended value of a standard 31 yr, 12k mi example, ~$49.9K 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? 64% 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 94 scored forecasts: 64% got the direction right, median value error ±20%.
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 (high conviction — 79% of weighted drivers agree), driven mainly by Gold (futures) and M2 Money Supply, 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.
