What to check on a used iQ

The parts that come up most often in Toyota iQ MOTs, and how to look at them on a viewing.

  1. Tyres
    Check the tread across the full width of every tyre, including the inner edge, and look for cuts and bulges in the sidewalls.
  2. Brake discs and pads
    Ask when the discs and pads were last replaced, and look through the wheel for a raised lip on the edge of the disc.
  3. Brake pipes and hoses
    Look underneath at the metal brake pipes for heavy rust, and at the rubber hoses for cracks or bulges.
  4. Coil springs
    Compare the gap between each tyre and its wheel arch. A corner sitting lower than the others can mean a broken spring.
  5. Wipers, washers and windscreen
    Run the wipers and washers, and look for chips or cracks in the windscreen, above all in front of the driver.

How these figures are made. We counted every initial MOT test (not retests) of cars and light vans in Great Britain in 2023 from the DVSA anonymised MOT dataset, 33,842,940 tests in all. Pass rate is the share of initial tests that ended in a pass, counting faults fixed during the test. Age is whole years from first registration to the test, so a car having its first MOT a few weeks early counts as 2.

Like-for-like pass rates average each model's pass rate at ages 3 to 10 with the same age mix for every model, so a model is not flattered by a young fleet or penalised by an old one. Models are grouped by the first word of the DVSA model name, and names that cover several models are left out.
