Chevrolet SS Sedan (Holden Commodore)
This is a low-confidence read for the Chevrolet SS Sedan market, given the thin data state. Indicators show an undervaluation score of 63.0, a speculation opportunity of 62.32, and a depreciation risk of 38.97, while forecasts suggest an 'up' direction with 0.49-0.5 probability but a volatile regime across all horizons. The High-Yield Bond Spread is the strongest leading indicator, showing a -0.74 correlation with a 12-month lead.
What It's Actually Worth
Blended value of a standard 9 yr, 46k mi example, ~$44.7K 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 37 scored forecasts: 57% got the direction right, median value error ±12%.
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.

No-lookahead: predictions are made before each auction closes; the scorecard grades confirmed sold auctions only (no-sales excluded). A modeled estimate, not a guarantee.

Lead Indicator Forecast
Some indicators move before this market does. Trade-Weighted Dollar Index has historically led it by about 10 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 (high conviction — 77% of weighted drivers agree), driven mainly by Trade-Weighted Dollar Index and U. Michigan Consumer Sentiment, though Advance Retail Sales 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 2016
$100K invested 2016-05 → today (10.2 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).
