What It's Actually Worth

Blended value of a standard 3 yr, 4k mi example, ~$48.5K 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.

Where We Think It's Headed

Lead Indicator Forecast

Some indicators move before this market does. 2-Year Treasury Yield 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.

$48.4K now +21mo 2021-09 $76.2K $46.0K
BECAUSE 2-Year Treasury Yield rose 13%. THEREFORE, given its usual 21-month head start, we expect little change — about −0% (≈ −$90) over the next 21 months. Confidence: Moderate (correlation -0.89, 20 months overlap).

If You’d Bought in 2021

$100K invested 2021-09 → today (5.1 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 Ford Mustang (S550) Mach 1 roughly 0.6×'d your money (a real 47% LOSS to inflation). It LAGGED the stock market by about 67% — 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.)
