The short version

Porsche is expanding its Sonderwunsch customization division to focus on complex, bespoke one-off builds rather than only paint and trim options.
Bespoke vehicle builds take approximately three years, starting with a $150,000 concept fee and base construction costs near $2 million.
Future one-off projects are scheduled for release in the coming months and years, with the company noting customer interest in four-door models.
