Case in point, this 2023 Peterbilt 389 Day Cab (now a Custom Sleeper), up for grabs for the grand total of $409,900, which is pretty much what you’d pay today for a new Ferrari Purosangue.

This 2017 Peterbilt Bolt Ultra was converted from a working semi-truck to a seven-seat luxury truck and, if you have $349,900, you can currently buy it on Facebook Marketplace.

Rush Truck Centers secured the final Model 389 with a winning bid of $1.5 million in an auction hosted by Peterbilt and attended by its dealer body at the 2023 Peterbilt dealer meeting.

Participants will have the chance to win the last Peterbilt Model 389X ever produced, and the only one that is a model year 2025. The 389 is being replaced by the Model 589 introduced last year.
