Mercedes-Benz E63 AMG S (W213, M177)
Flagged undervalued because sell-through 100%, and asking -7% vs historic sold.
What It's Actually Worth
Blended value of a standard 6 yr, 37k mi example, ~$77.9K 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? 51% 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 37 scored forecasts: 51% got the direction right, median value error ±14%.
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.
