The Falcon GTHO Phase 4 is one of the rarest muscle cars ever built by Ford. Only 4 were ever made and 3 are beleived to still exist. 3 were purpose built for production car racing and only one made it through the production line before the program was cancelled due to the "muscle car scare" in Australia.

It is to Australia, what the Mustang Boss 429 is to the USA - The ultimate muscle car.
