Rolling chassis

It is equipped with running gear (engine and drivetrain) and ready for delivery to a coachbuilder to be completed.

Historically, bespoke luxury automobiles were finished inside and out to an owner's specifications by a coachbuilder, and specialty vehicles (such as fire engines) were outfitted by firms devoted to that task.

Prior to unibodied vehicles, the rolling chassis stage was common to the manufacture of all motorcars.

Over time top luxury automakers absorbed one or more of their vendors and moved vehicle finishing in-house.

The rolling chassis is delivered to the commercial body maker, coachbuilder, or bulk transporter on its own wheels, under its own power.
