Given the 'thin' data_state, this market read for the BMW E30 M3 Evolution is low-confidence, reflected by a score of 0.613. Despite a high overvaluation score of 89.88, the market forecast signals an 'up' direction with probabilities from 0.59 at 6 months to 0.7 at 24 months, though all regimes are projected as 'volatile', with Advance Retail Sales (corr 0.93, 14-month lead) serving as the strongest leading indicator.
What It's Actually Worth
Blended value of a standard 36 yr, 57k mi example, ~$141K 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.

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 (moderate conviction — 52% of weighted drivers agree), driven mainly by Real Disposable Income per Capita and 30-Year Mortgage Rate, though 30-Year Mortgage Rate points the other way.
⚠ The price trend and leading indicators disagree — momentum may be running ahead of the fundamentals.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
