Honda CB750/CB750A
Given the "thin" data state, this read carries low confidence. The Honda CB750/CB750A market currently shows an undervaluation score of 65.04, alongside a depreciation risk of 51.01. Forecasts over 6, 12, and 24 months suggest an "up" direction with probabilities of 0.45, 0.44, and 0.42 respectively, all within a "volatile" regime. The strongest leading indicator identified is Gold (futures), which shows a strong negative correlation of -0.82 with a 3-month lead.
What It's Actually Worth
Blended value of a standard 51 yr, 14k mi example, ~$6.7K 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? 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 53 scored forecasts: 66% got the direction right, median value error ±33%.

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 higher over the next ~12 months (low conviction — 24% of weighted drivers agree), driven mainly by Initial Jobless Claims and S&P 500, though S&P 500 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.
