Given the thin data state, this read on the Pontiac Firebird (1970-1981) Formula market is low-confidence (0.71). The market currently registers a high depreciation risk at 70.74, despite a notable undervaluation score of 69.22 and low appreciation momentum at 25.7. The outlook for the next 6 to 24 months signals an "up" direction, though with probabilities ranging from 0.45 to 0.47, indicating a volatile regime; the High-Yield Bond Spread is the strongest leading indicator with a 0.74 correlation at a 20-month lead.
What It's Actually Worth
Blended value of a standard 50 yr, 49k mi example, ~$34.8K 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 (low conviction — 25% of weighted drivers agree), driven mainly by Ethereum (USD) and Personal Savings Rate, though Housing Starts 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.
