What to check before viewing
The model's most common MOT issues, turned into things you can ask about or look for.
Independent inspection
High priorityHave an independent specialist inspect the car before you commit.
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.
Shock absorbers
Worth checkingBounce-test each corner; check for oily streaks down the strut bodies.
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.
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.
