Pontiac Bonneville
The Pontiac Bonneville market outlook, with a confidence of 0.935, shows appreciation momentum at 73.4 but indicates a 0.51-0.52 probability of a downward trend in a volatile regime across the 6 to 24-month horizon. Liquidity is noted at 43.51, and the High-Yield Bond Spread is the strongest leading indicator, with an 18-month lead and -0.65 correlation.
What It's Actually Worth
Blended value of a standard 62 yr, 43k mi example, ~$20.0K 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? 66% 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 119 scored forecasts: 66% got the direction right, median value error ±33%.

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. High-Yield Bond Spread has historically led it by about 4 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 — 74% of weighted drivers agree), driven mainly by High-Yield Bond Spread and Initial Jobless Claims, though Initial Jobless Claims 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 2006
$100K invested 2006-01 → today (20.6 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).
What This Market Follows
Specialty-car prices don't move in a vacuum. These economic indicators have historically led this market — tap one to see it shifted forward by its lead time, overlaid on the value line.
High-Yield Bond Spread leads by about 18 months (moves against this market, correlation 0.54). Shown shifted forward 18 months so its turns line up with the market's.
