5. Pontiac G8 / Holden Commodore
The Pontiac G8 gave American enthusiasts a taste of Australian muscle by rebadging the Holden Commodore. This rear-wheel-drive sedan, built down under, arrived in North America boasting powerful V8 engines and sharp handling—qualities rarely found in its class at the time. With a new badge and a few styling tweaks, the Commodore became a standout Pontiac, reminding buyers that performance and excitement could still live in a family sedan. Source
