Greening Auto Company

What Greening Auto Company does

Greening Auto Company (GAC) is a family-owned custom automotive builder and specialty parts manufacturer founded in 1999 by Jesse and Jeff Greening, operating from a single facility in Cullman, Alabama. The company's primary business is the design, engineering, fabrication, and assembly of bespoke hot rods, muscle cars, classic vehicles, and roadsters, producing two to three full builds per year for individual collectors and automotive enthusiasts. Each project encompasses the complete build cycle — from initial sketches and CAD renderings through CNC machining, sheet metal fabrication, paint and body work, and final assembly — with notable projects including award-contending vehicles for Ridler, AMBR, and SEMA Battle of the Builders competitions.

Underlying production is an in-house technical stack centered on CAD design, Finite Element Analysis (FEA) validation for wheel engineering, CNC machining of 6061-T6 aluminum forgings and spun-forged barrels, and 3D printed metal parts for prototyping and unique components (notably used in the Greening 27 Roadster's functional suspension and interior pieces). Beyond full builds, GAC sells a small production parts line — LS Series Valve Covers (GE-01 at $1,195 and GE-02 at $1,295), GP/GS/GX Series Custom Wheels, and GL Series billet aluminum LED lights — representing standardized versions of components originally developed for bespoke builds. Specialty parts revenue is transactional unit-pricing, while custom builds are quote-based projects typically spanning multi-year engagements, with the company's only distribution channels being direct engagement via phone/email and showcase appearances at SEMA, Goodguys, Ridler, and AMBR competitions.
