RS500 Cosworth (1987 to 1987)

The Ford Sierra RS500 Cosworth (1987) stands as the undisputed king of the Sierra lineage in the 2026 Australian market, revered as the ultimate homologation special that famously conquered Bathurst. Only 500 were ever converted by Tickford in the UK, featuring a reinforced YBD engine with a larger Garrett turbo and an iconic "double-decker" rear spoiler to meet Group A racing demands. Because of their immense local motorsport pedigree, market values for genuine road-going examples are among the highest for any four-cylinder Ford, typically ranging from $185,000 to $340,000 AUD, while ex-race cars with verified podium history from teams like DJR or B&H can soar beyond $450,000 AUD. The desirability of the RS500 is absolute, attracting an elite buyer pool of high-net-worth collectors and homologation purists who view the car as a blue-chip investment. Locally, liquidity is highest for pristine survivors in Black, White, or Moonstone Blue that retain their factory-original 224hp specifications, as the 2026 market places a significant premium on documented provenance and untouched mechanical integrity over the many replicas currently in circulation.
