Buick Riviera
The Buick Riviera market signals an overvaluation score of 55.69 and depreciation risk at 61.61, with liquidity scoring 21.73. Forecasts suggest a 'down' direction with probabilities around 0.5 to 0.51 over 6, 12, and 24 months, indicating a volatile regime; the strongest leading indicator is the High-Yield Bond Spread, with a 0.55 correlation over a 9-month lead.
What It's Actually Worth
Blended value of a standard 52 yr, 48k 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? 61% 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 155 scored forecasts: 61% got the direction right, median value error ±24%.
