Porsche 911 (964)
The Porsche 911 (964) market exhibits modest appreciation momentum at 34.93 and a depreciation risk score of 54.74, alongside a liquidity score of 46.0. While the forecast indicates a slightly upward direction with probabilities ranging from 0.52 to 0.55 over the next 6 to 24 months, this trend is anticipated within a volatile regime. The strongest leading indicator is the Case-Shiller National Home Price, which shows a correlation of 0.84 with an 18-month lead.
What It's Actually Worth
Blended value of a standard 35 yr, 64k mi example, ~$97.0K 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? 57% 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 77 scored forecasts: 57% got the direction right, median value error ±52%.
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.
