Wine Country Standard

The Same Standard You Apply to Everything Else.

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.

What Commission-Level Means

Executed to a Standard
That Can't Be Rushed.

Every Mayne Designs build — whether $75K or $250K+ — follows the same method. No shortcuts at any investment level.

01
Rendering Before Any Work Begins
Before a tool touches your car, you see a full rendering. Color, stance, wheels, every visual choice confirmed before fabrication begins. This is how it should be done. It's how Mayne Designs does it.
02
Personal Communication Throughout
Markus personally communicates throughout every build — photos, updates, questions, milestone reviews. You are never left wondering. This level of transparency is rare in the industry. At Mayne Designs it's standard.
03
Documented and Delivered
Every build is documented in full and delivered with a complete build record. Napa and Sonoma clients who value provenance will appreciate that the story of their build is preserved as carefully as the build itself.
For Napa & Sonoma Collectors

The Statement Build.
No Ceiling.

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.

$250K+
Statement Build
No ceiling. No compromises. One-off custom fabrication, show-level paint, 700+ HP powertrain, magazine-ready documentation. The build Mayne Designs was built to deliver.
Black Tie 1969 Camaro — commission-level build for Napa Sonoma

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.
