Dodge Viper GTS
Flagged undervalued because sell-through 95%.
What It's Actually Worth
Blended value of a standard 27 yr, 12k mi example, ~$80.1K 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? 58% 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 78 scored forecasts: 58% got the direction right, median value error ±27%.
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. Gold (futures) has historically led it by about 22 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 higher over the next ~12 months (moderate conviction — 51% of weighted drivers agree), driven mainly by Gold (futures) and 2-Year Treasury Yield, though Ethereum (USD) 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 2012
$100K invested 2012-05 → today (14.2 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).
