2004 Holden Monaro Marilyn Concept

The 2004 Holden Monaro Marilyn Concept was a striking convertible adaptation of the V2 Monaro, engineered by Tom Walkinshaw Racing (TWR). Built as a fully operational prototype, the Marilyn showcased Holden’s exploration into a drop-top muscle car, blending the Monaro’s powerful V8 performance with an open-air driving experience. Despite its potential appeal, the concept never made it to production, leaving the Marilyn as a one-off glimpse into what could have been a bold addition to Holden’s lineup.
