What It's Actually Worth

Blended value of a standard 6 yr, 4k mi example, ~$75.1K 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. U. Michigan Consumer Sentiment has historically led it by about 12 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.

$77.0K now +12mo 2021-03 $78.2K $54.5K
BECAUSE consumer sentiment fell 14%. THEREFORE, given its usual 12-month head start, we lean UP — about +3% (≈ +$1,960) over the next 12 months. Confidence: High (correlation +0.60, 42 months overlap).
