Typical asking-price range (middle 50% of listings) from 951 priced Peterbilt 579 listings across 33 dealers, observed over the last 180 days. These are asking prices from live listings — not sale prices. Years with too few priced listings, or dominated by one dealer, show “insufficient data.” How we calculate this →

The 2020 Peterbilt 579 powered by the MX 13 Liter is currently represented by 2 active listings on TruckRadar. Listed units show a median odometer reading of about 423,375 miles. Most are configured as conventional cab with tandem rear axle drivetrains, commonly paired with PACCAR Automatic 12 Speed and PACCAR Endurant 12 Speed transmissions. Geographically, the largest concentrations of 2020 579 inventory sit in Arkansas and Oklahoma. TruckRadar is not publishing a median asking price for this configuration because its priced listings are concentrated with a single dealer, so a median would reflect one seller's pricing rather than the broader market. To gauge pricing, review the individual active listings below — each shows the dealer's own asking price directly. Buyers comparing this configuration often also evaluate the 389 and 567. All figures reflect active dealer listings on TruckRadar and are asking prices, not sale prices.
