What to check before viewing
The model's most common MOT issues, turned into things you can ask about or look for.
Brake pipes and hoses
High priorityLook under the car for corrosion or chafing on the rigid brake pipes near the rear axle.
Brake discs
High priorityAsk for the date and mileage of the last disc replacement; visually check for a deep wear lip and rust pitting on each disc.
Suspension bushes and joints
Worth checkingListen for knocks over speed bumps and ask about recent control-arm or anti-roll-bar work.
Tyres
Worth checkingCheck tread depth across the full width on all four; uneven wear suggests alignment or suspension issues.
Leaks
Worth checkingInspect the leaks carefully and ask the seller for repair history.
Vehicle-specific check
Worth checkingCheck the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.
