Napa and Sonoma clients who commission Mayne Designs builds expect the same standard in their cars as they demand in everything else. Commission-level Pro Touring and restomod builds, by appointment, for collectors who don't compromise.
Napa Valley and Sonoma County are home to collectors who understand quality from every angle — the patience required to get something right, the cost of cutting corners, the difference between something good and something exceptional. That instinct applies to cars, too.
Mayne Designs builds commission-level Pro Touring and restomod muscle cars for Napa and Sonoma clients who want a build that reflects their standard. Not a factory car. Not a flip. A commission — built with the same intentionality that defines the best of wine country.
Operating by appointment across Napa, Sonoma, Santa Rosa, Healdsburg, Petaluma, and St. Helena — Markus travels to you for the consultation, and manages pickup and delivery with the same care as every other phase of the build.
Every Mayne Designs build — whether $75K or $250K+ — follows the same method. No shortcuts at any investment level.
Napa and Sonoma clients are among the strongest candidates for Mayne Designs' Statement Build tier. SEMA and Goodguys show-level execution. Full custom fabrication. Twin-turbo or supercharged power at 700+ HP. Magazine and show-ready finish. Covered media and documentation.
This is the build for the client who has spent decades thinking about a specific car — and is now in a position to commission it right. It takes 12 to 18 months. It earns shows. It ends up in print. And it remains in the family for generations.
Markus didn't just build my car — he built my vision. The rendering blew me away before he ever touched the Camaro. The finished car won best in show at Goodguys.
Best in show at Goodguys Pleasanton. Ground-up Pro Touring with show-quality paint and the performance to support the visual.
