Audi S6 (C7)
Given a 'thin' data state, our read for the Audi S6 (C7) market is low-confidence. Current scores show depreciation risk at 40.74, undervaluation at 57.75, and liquidity at 60.6. The 6-month outlook points to a 'down' direction with 0.54 probability in a 'volatile' regime, with Gold (futures) being the strongest leading indicator, correlated at 0.86 over a 23-month lead.
What It's Actually Worth
Blended value of a standard 10 yr, 58k mi example, ~$25.5K 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.
Did our model work? 48% direction calls right
Each faint amber line is a forecast we would have made at that point in the past (12-mo horizon), drawn against what actually happened (blue). Over 23 scored forecasts: 48% got the direction right, median value error ±17%.
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. Consumer Discretionary ETF (XLY) has historically led it by about 14 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.
Crystal Ball — What Leading Indicators Signal
Distinct from the trend forecast above: this blends all 8 leading indicators (each at its own lead time, de-duplicated so correlated ones don't double-count) into one signal. Leading indicators are collectively signaling higher over the next ~12 months (high conviction — 100% of weighted drivers agree), driven mainly by Consumer Discretionary ETF (XLY) and U. Michigan Consumer Sentiment.
Are the indicators agreeing?
Each bar is one driver's current push; longer = more weight. All one side = high conviction; split = low.
If You’d Bought in 2021
$100K invested 2021-09 → today (5.0 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).
