What It's Actually Worth
Blended value of a standard 18 yr, 10k mi example, ~$73.7K 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.

━ actual╱ past predictions (ghosts)
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.

If You’d Bought in 2013

Lost ground to inflation. The Dodge Viper SRT-10 Coupe roughly 1.2×'d your money (a real 16% LOSS to inflation). It LAGGED the stock market by about 80% — the same money in the S&P 500 would be larger. It trailed housing (-48%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
