The work

Step by step.

  1. 01

    Arrival at the workshop.

    The starting point: the 930 Turbo Cabriolet as it arrived in Mougins, before any strip-down.

    The bare shell.

    Cabin, front trunk, wheel arches: everything is stripped back to metal. The body shows itself as it is.

    Paint, then finishing.

    The shell goes into the booth on its rotisserie. Polishing then gives the silver its taut reflections back.
