The Porsche 911 GT3 (991) GT3 RS market shows appreciation momentum at 51.06 and liquidity at 52.88, with an overvaluation score of 55.88 and depreciation risk at 45.31. Signals suggest a potential "up" direction with probabilities ranging from 0.5 to 0.55 across the 6, 12, and 24-month horizons, though a "volatile" regime is indicated. The strongest leading indicator is the Trade-Weighted Dollar Index, with a correlation of -0.57 over a 16-month lead.

What It's Actually Worth

Blended value of a standard 7 yr, 6k mi example, ~$214K 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.

Lead Indicator Forecast

Some indicators move before this market does. Trade-Weighted Dollar Index has historically led it by about 16 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.

$220K now +16mo 2018-08 $266K $200K
BECAUSE the US dollar fell 5%. THEREFORE, given its usual 16-month head start, we lean UP — about +2% (≈ +$5,343) over the next 16 months. Confidence: High (correlation -0.56, 45 months overlap).

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 lower over the next ~12 months (high conviction — 79% of weighted drivers agree), driven mainly by Trade-Weighted Dollar Index and 10Y-2Y Yield Spread, though Bitcoin (USD) points the other way.

⚠ The price trend and leading indicators disagree — momentum may be running ahead of the fundamentals.

It LAGGED the stock market by about 73% — the same money in the S&P 500 would be larger. It trailed housing (-51%). (Price only — a real round-trip also loses ~10–20% to buy/sell fees and carrying costs.)
