Aston Martin DB4
This is a rare market — roughly 11 sales per year documented since 2003 (261 total across all sources).
Tracking 6 sales in the last 90 days — the modeled signal will appear here on the next nightly rebuild.
What It's Actually Worth
Blended value of a standard 64 yr, 21k mi example, ~$279K 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? 70% 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 86 scored forecasts: 70% got the direction right, median value error ±84%.
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.
Auction Scorecard gavel in range 7 in 10
