Unlike the median asking price shown above, True Value is anchored to 2 recent confirmed sales, normalized for mileage, and blends auction hammer prices (grossed up for buyer's premium) with real-world asking behavior.
Sellers are currently asking a median of $18,000 — about 120% above what these cars have actually been selling for. That gap favors patient buyers: negotiate from the sold data, not the ask.
