BMW 5-Series (E39) M5
Flagged undervalued because -51% vs 2-yr avg, -51% vs 3-yr trend, and sell-through 99%.
What It's Actually Worth
Blended value of a standard 24 yr, 95k 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? 62% 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 89 scored forecasts: 62% got the direction right, median value error ±28%.
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.
