What It's Actually Worth
Blended value of a standard 2 yr, 13k mi example, ~$82.8K 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.
