It was a decade ago that GM imported the Holden Monaro from Australia and badged it as the Pontiac GTO. The Monaro-GTO did bear similarities to the classic GTOs of the 1970s, being based on a plain-jane midsize coupe and sporting a high-output V-8. Nevertheless, the GTO met lackluster reviews, complaints centering on its heaviness (3,700 lbs.) and drab design. GM tried to spiff up the GTO for ‘05, installing a 6.0 L V-8 (up from 5.7) and hood scoops. It wasn’t enough—the GTO ran for one more year before getting the axe. It’s generally considered a collectible today.
