Ferrari 328
Given thin underlying data, this outlook for the Ferrari 328 market carries a low-confidence read. Forecasts for the next 6, 12, and 24 months consistently point to a volatile regime with a downward trend, showing probabilities between 0.44 and 0.48. The strongest leading indicator is the Case-Shiller National Home Price, with a correlation of 0.86.
What It's Actually Worth
Blended value of a standard 37 yr, 24k mi example, ~$124K 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 101 scored forecasts: 59% got the direction right, median value error ±42%.
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.
