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

Worth checkingCheck the car’s number plate on MOT Wise to see its own MOT history and any recalls for its build years.
Windscreen
If you have timeInspect for chips and cracks in the wiper sweep area (Zone A) — these will fail an MOT.
