Audi RS4 (B7)
Given the thin data state, this market read for the Audi RS4 (B7) is low-confidence. Despite this, appreciation momentum is noted at 62.33, with depreciation risk at 39.31, and forecasts indicate an upward direction with 0.56 probability over 6 months, rising to 0.66 over 24 months, all within a volatile regime. The strongest leading indicator observed is the Case-Shiller National Home Price, showing a 0.85 correlation with a 21-month lead.
What It's Actually Worth
Blended value of a standard 17 yr, 86k mi example, ~$30.3K 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? 59% 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 41 scored forecasts: 59% got the direction right, median value error ±14%.

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 Gold (futures) and Nonfarm Payrolls (jobs).
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
