The Ford Sierra's most common MOT issues, turned into things to ask about or look for.

Brake pipes and hoses

High priority

Look under the car for corrosion or chafing on the rigid brake pipes near the rear axle.

Leaks

Worth checking

Inspect the leaks carefully and ask the seller for repair history.

Suspension bushes and joints

Worth checking

Listen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.

Suspension

Worth checking

Inspect the suspension carefully and ask the seller for repair history.

Tyres

Worth checking

Check tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.
