What It's Actually Worth

Blended value of a standard 54 yr, 9k mi example, ~$4.7K 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.

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.

Lead Indicator Forecast

Some indicators move before this market does. Housing Starts 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.

$4.6K now +10mo 2014-01 $9.8K $1.5K
BECAUSE Housing Starts fell 18%. THEREFORE, given its usual 10-month head start, we lean DOWN — about −3% (≈ −$134) over the next 10 months. Confidence: Moderate (correlation +0.46, 45 months overlap).

If You’d Bought in 2014

$100K invested 2014-01 → today (12.5 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).

Lost ground to inflation. The Honda CB450/CL450/CB500 Twin roughly 0.6×'d your money (a real 58% LOSS to inflation). It LAGGED the stock market by about 89% — the same money in the S&P 500 would be larger. It trailed housing (-71%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
