What It's Actually Worth
Blended value of a standard 11 yr, 7k mi example, ~$153K 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? 100% direction calls right

━ 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 2017
$100K invested 2017-01 → today (9.8 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).

Roughly tracked inflation — flat in real terms. The Dodge Viper (2013-2017) GTS roughly 1.4×'d your money (a real, inflation-adjusted 1.0× gain). It LAGGED the stock market by about 64% — the same money in the S&P 500 would be larger. It trailed housing (-24%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
