I remember in the early 2000s there was a big push to deshittify delivery pizza. Companies were all advertising how they were now sending out their pizza in insulated bags. Dominos went particularly heavy, advertising a purpose built delivery vehicle with a built in warming oven (not sure if this was ever real or just for advertising) and a big emphasis on how they reformulated the entire menu to taste better.

When I worked there they had hot boxes drivers would carry in their car. There was an alcohol burner in it that somewhat kept it warm. They switched to insulated bags about a year after I started.

The stores usually had one or two company cars, a hatchback like a Ford Escort, painted up with the Domino’s logo. It was not equipped with any special pizza warmer. But most drivers used their own car. They got an hourly wage, a percentage of the order total if they used their own car, and tips.

Maybe Domino's had another delivery vehicle in the 2000s, but one of the 10 Tritan Domino's delivery vehicles from the '80s sold at auction a few weeks ago for US $45,000.

The vehicle was real. There is (or was) a series on YouTube about someone who bought one that had been salvaged and wanted to repair it for his own use but ended up getting various legal threats from Domino's, claiming he obtained the vehicle illegally or planned to misuse their branding.
