What It's Actually Worth
Blended value of a standard 1 yr, 1k mi example, ~$414K 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. Russell 2000 (small cap) has historically led it by about 21 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.
BECAUSE Russell 2000 (small cap) rose 19%. THEREFORE, given its usual 21-month head start, we lean DOWN — about −1% (≈ −$3,973) over the next 21 months. Confidence: Moderate (correlation +0.87, 23 months overlap).
If You’d Bought in 2023
$100K invested 2023-12 → today (2.8 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).

Lost ground to inflation. The Porsche 911 GT3 (992) GT3 RS roughly 1.0×'d your money (a real 12% LOSS to inflation). It LAGGED the stock market by about 43% — the same money in the S&P 500 would be larger. It trailed housing (-11%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
