Chevrolet Impala (1965-1970)
Flagged undervalued because asking -17% vs historic sold, and inventory -0%.
What It's Actually Worth
Blended value of a standard 58 yr, 51k mi example, ~$26.3K 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? 60% 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 134 scored forecasts: 60% got the direction right, median value error ±23%.
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.
