Audi RS4 (B7)
Due to the thin data state, this market read for the Audi RS4 (B7) is low-confidence. Current metrics indicate appreciation momentum at 63.41 and depreciation risk at 35.81, while overvaluation scores 65.74. An upward price direction is signaled for the next 6 to 24 months with probabilities from 0.56 to 0.64, though price action is expected to be volatile; the strongest leading indicator is the Case-Shiller National Home Price, showing a 0.94 correlation over 21 months.
What It's Actually Worth
Blended value of a standard 18 yr, 88k mi example, ~$29.7K 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? 76% 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 42 scored forecasts: 76% got the direction right, median value error ±10%.
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.

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 (high conviction — 100% of weighted drivers agree), driven mainly by 10Y-2Y Yield Spread and Bitcoin (USD).
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
