Mercedes-Benz S65 AMG (V12 biturbo)
Flagged undervalued because asking -23% vs historic sold, sell-through 91%, -26% vs 2-yr avg, and -27% vs 3-yr trend.
What It's Actually Worth
Blended value of a standard 14 yr, 53k mi example, ~$54.0K 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? 46% 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 39 scored forecasts: 46% got the direction right, median value error ±22%.
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.

No-lookahead: predictions are made before each auction closes; the scorecard grades confirmed sold auctions only (no-sales excluded). A modeled estimate, not a guarantee.

Lead Indicator Forecast
Some indicators move before this market does. Silver has historically led it by about 5 months — so its recent move implies where prices head next (dashed). The solid green line is actual value through today; the shaded path is what the lead implies.
Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 8 leading indicators (each at its own lead time, de-duplicated so correlated ones don't double-count) into one signal. Leading indicators are collectively signaling lower over the next ~12 months (high conviction — 100% of weighted drivers agree), driven mainly by Silver and VIX Volatility Index.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
If You’d Bought in 2021
$100K invested 2021-05 → today (5.2 yrs), this car vs where else you could've put the money. Rebased to 100 at the start; the dashed line is inflation (break-even).
What This Market Follows
Specialty-car prices don't move in a vacuum. These economic indicators have historically led this market — tap one to see it shifted forward by its lead time, overlaid on the value line.
Silver leads by about 5 months (moves against this market, correlation 0.49). Shown shifted forward 5 months so its turns line up with the market's.
