A free inspection you did not pay for

When a car is sold as an MOT failure, the failure sheet lists exactly what a tester found wrong. That is a free, professional inspection you did not have to pay for, and reading it properly is one of the quickest ways to spot a bargain or a trap before you bid.

Sort the list into cheap and dear

Go down the sheet and split it. Lamps, wipers, washers, tyres, brake pads, a track rod end: cheap consumables you can sort for very little. Corrosion to a load-bearing area, a catalytic converter or DPF, a steering rack, or multiple suspension items across both axles: these cost real money and change the maths.

Read between the lines

One failure often implies others. Uneven tyre wear hints at alignment or suspension. A single corrosion advisory can mean more rot nearby. A DPF fail on a diesel can mean a car used only for short trips, which brings its own problems. Treat the sheet as clues, not just a shopping list.

Dangerous versus major

Modern sheets grade each defect as dangerous, major or minor. Dangerous items, most often tyres and brakes, are both the most urgent and usually the cheapest to fix, so they should reassure rather than scare you. It is the major structural and mechanical items that decide whether the car is worth buying.

Turn it into a number

Once you have split the sheet, put the car and the repairs through the Analyzer. It turns the list of defects into a repair estimate, adds the fees and the market value, and tells you the most you can pay and still make money. That is the difference between buying an MOT failure on a hunch and buying it on the numbers.
