What to check on an Ford Sierra

These are the known weak points of the Sierra. Every seller here answers them one by one before their car can go live — so you can compare two cars on the same terms.

  • Rust at the rear arches, sills, front wings, floorpan and around the sunroof
  • Head gasket and turbo condition
  • Gearbox and differential wear
  • Wiring loom and ECU
  • Original body panels and paint depth
  • Cambelt history

Is it genuine? What buyers check on an SierraRS Cosworth and Sapphire RS Cosworth have unique VINs beginning with specific sequences and a factory-fitted YB engine with its own number. Replica Cosworths built from standard Sierras are extremely common and are worth a fraction.

Buying a Ford Sierra RS500 Cosworth

The Sierra was built between 1982 and 1993, which is why it belongs here: 80s90s.Club lists a car when its generation was in production at any point between 1980 and 1999. A 1982 car and a 1993 car are both welcome; what decides is the generation, never the year on its own.

Every Sierra listed here carries the same checklist, answered by the seller line by line, and a Logbook tied to the car's chassis number rather than to whoever happens to own it. Contact the seller directly — we never hold your money and never take a cut.
