Custom Muscle Car Builds Serving the Bay Area

Commission-level Pro Touring builds for Bay Area clients who know what they want and expect it built right. Serving San Francisco, Oakland, San Jose, Marin and the entire region by appointment.

Bay Area Car Culture

Where Precision Meets Passion.

The Bay Area has always had a serious car culture — an appreciation for engineering, for aesthetics, for things built with intention. Bay Area clients who come to Mayne Designs aren't looking for a quick build. They're looking for a machine that reflects how they think.

Serving San Francisco, Oakland, San Jose, Marin, and surrounding counties, Mayne Designs handles Bay Area commissions the same way every build is handled: by appointment, with a rendering before a single tool touches the car, and with Markus personally involved at every stage.
