BMW 5-Series (E39) M5
Flagged undervalued because sell-through 98%.
What It's Actually Worth
Blended value of a standard 24 yr, 95k mi example, ~$33.2K 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 91 scored forecasts: 64% got the direction right, median value error ±28%.

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 — 77% of weighted drivers agree), driven mainly by 10-Year Treasury Yield and M2 Money Supply, though VIX Volatility Index 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.
