Porsche 356 Carrera
Due to a thin data state, this market outlook for the Porsche 356 Carrera is low-confidence. Current data signals high overvaluation at 86.38 and a depreciation risk of 64.64, with appreciation momentum at 46.19. The forecast indicates a potential 'up' direction with a 0.48 probability over 6, 12, and 24 months in a volatile regime, with the High-Yield Bond Spread being the strongest leading indicator at 0.75 correlation with a 3-month lead.
What It's Actually Worth
Blended value of a standard 65 yr, 32k mi example, ~$167K 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? 51% 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 89 scored forecasts: 51% got the direction right, median value error ±41%.

Lead Indicator Forecast
Some indicators move before this market does. Ethereum (USD) has historically led it by about 2 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 (low conviction — 20% of weighted drivers agree), driven mainly by Bitcoin (USD) and Nasdaq Composite, though Bitcoin (USD) 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 2003
$100K invested 2003-08 → today (22.9 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).
