Back at the set, while there's no car to work on, the Overhaulin' team gets busy with all the subassemblies that will not be replaced. As a rule of thumb, just about every car gets a new drivetrain, suspension, brakes, wheels, and tires, whereas the interior is usually kept mostly stock with fresh trim and carpet and some paint. Of course, this can vary depending upon what Chip wants to do with the car. Wiring harnesses, hinges, brackets, steering columns, and so on are usually cleaned, painted, and prepped for installation. Cherie Westrich handles much of the interior parts on the overhauled cars.
