BMW 5-Series (E39) M5
Flagged undervalued because -50% vs 2-yr avg, -49% vs 3-yr trend, and sell-through 97%.
What It's Actually Worth
Blended value of a standard 24 yr, 95k mi example, ~$32.7K 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? 58% 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 90 scored forecasts: 58% got the direction right, median value error ±29%.
