In the UK, it was the definitive family car, but survivors are now battling aggressive body rust and tired steering components, pushing them into the banger or enthusiast category.

Buying Tips for the Ford Focus Mk1 (C170)

  • Rust is the ultimate killer; check the wheel arches, bottoms of the doors, sills, and the rear subframe very carefully.
  • Check the instrument cluster; speedometers frequently fail or drop to zero due to a faulty vehicle speed sensor in the gearbox.
  • Listen for knocking from the rear suspension over bumps, which indicates the trailing arm bushes (crucial to the Control Blade setup) have failed.
  • On the 1.6 Zetec engine, ensure the cambelt has been changed and check the spark plug wells for water ingress from leaking washer jets.
  • Verify the central locking works on all doors; the door latch mechanisms frequently fail, refusing to lock or unlock.
  • Test the power steering for leaks or heavy feeling, particularly around the rack ends, which is a common MOT failure.
