Mercedes-Benz SLS AMG
Flagged undervalued because -56% vs 2-yr avg, -53% vs 3-yr trend, inventory -0%, and sell-through 98%.
What It's Actually Worth
Blended value of a standard 13 yr, 9k mi example, ~$212K 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? 63% 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 64 scored forecasts: 63% got the direction right, median value error ±50%.
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. 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.

Lead Indicator Forecast
Some indicators move before this market does. High-Yield Bond Spread has historically led it by about 8 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 — 77% of weighted drivers agree), driven mainly by LVMH (luxury proxy ADR) and Case-Shiller Home Price, though Real Disposable Income per Capita points the other way.
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 2013
$100K invested 2013-05 → today (13.2 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.
LVMH (luxury proxy ADR) leads by about 16 months (moves with this market, correlation 0.84). Shown shifted forward 16 months so its turns line up with the market's.
