What It's Actually Worth
Blended value of a standard 7 yr, 2k mi example, ~$683K 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? 69% 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 36 scored forecasts: 69% got the direction right, median value error ±21%.

Lead Indicator Forecast
Some indicators move before this market does. Trade-Weighted Dollar Index has historically led it by about 9 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 — 79% of weighted drivers agree), driven mainly by Trade-Weighted Dollar Index and VIX Volatility Index, though WTI Crude Oil 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 2020
$100K invested 2020-03 → today (6.8 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).
