Datsun 280Z
Due to a thin data state, this read on the Datsun 280Z market is low-confidence. The market registers an overvaluation score of 55.6 and a liquidity score of 52.4. Forecasts indicate a potential upward direction with probabilities ranging from 0.51 to 0.54 over the next 6 to 24 months, within a volatile regime; the strongest leading indicator is the Consumer Discretionary ETF (XLY) with a 0.59 correlation leading by 21 months.
What It's Actually Worth
Blended value of a standard 47 yr, 51k mi example, ~$23.6K 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 87 scored forecasts: 59% got the direction right, median value error ±40%.
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.
