Blended value of a standard 63 yr, 27k mi example, ~$156K 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.

No-lookahead: predictions are made before each auction closes; the scorecard grades confirmed sold auctions only (no-sales excluded). A modeled estimate, not a guarantee. 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 2004
$100K invested 2004-08 → today (21.8 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).
━ This car $192K━ Housing $215K
Roughly tracked inflation — flat in real terms. The Porsche 356 Carrera roughly 1.9×'d your money (a real, inflation-adjusted 1.1× gain). It trailed housing (-11%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
