TruckRadar’s asking-price index reports the typical asking price of used commercial trucks by make, model, and model year, computed from active dealer listings on TruckRadar. These are asking prices from live listings — not transaction, auction, or sold prices. We report only what we can directly observe: what dealers are asking today. We never model, estimate, or interpolate a number to fill a gap; a model year without enough real data is labeled “insufficient data,” not guessed.
For each model year of a truck, we take the asking prices of listings that were active within the last 180 days and report the range covering the middle 50% of them — the 25th percentile to the 75th percentile. We show a range rather than a single number because asking prices vary widely with mileage, condition, sleeper configuration, and specification.
A listing is “priced” when it shows a real dollar figure between $1,000 and $500,000. Listings marked “Call for Price,” and figures outside that sanity band, are excluded. Within each model year we also drop individual prices that are statistical outliers (a robust modified z-score above 3.5), so one mislabeled or salvage unit cannot distort the range.
A model year is published only if it clears every test below. Otherwise it shows “insufficient data.”
We do not report sold prices, transaction prices, or estimated values — we do not have that data and will not manufacture it. For editorial context on how used Class 8 trucks hold their price over time, see our used truck resale guide. The asking-price ranges themselves appear on each model’s market page, for example the Freightliner Cascadia pages.
