Advisories to look for in a Suzuki Alto's MOT history

An advisory is a tester's warning that something is wearing but has not failed yet. These are the ones written most often on the Suzuki Alto, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.

  • Rigid brake pipes: corroded, covered in grease or other material327.1
  • Tread depth: worn close to legal limit/worn on edge258.8
  • Coil spring: corroded250.4
  • Suspension arms: pin or bush worn but not resulting in excessive movement239.5
  • Tyres: slightly damaged/cracking or perishing175.8
  • Brake discs: worn, pitted or scored, but not seriously weakened86.1

Checking a used Suzuki Alto before you buy

Against cars of the same age, the Suzuki Alto fails more often than average on lights and electrics and windscreen, wipers and mirrors. Start there.

  • Lights and electrics

    Walk round the car with every light on: headlights on dip and main beam, indicators, brake lights, fog lights and the number plate lamp. A pattern of electrical faults costs more than a bulb.

  • Windscreen, wipers and mirrors

    Look for chips or cracks in the driver's line of sight, and test the wipers and washers. Windscreen damage in the swept area is an MOT failure.

Averages only take you so far. The specific car's MOT history shows whether it has already failed on any of these, how often advisories were ignored, and whether the mileage climbs steadily from test to test. Read our guide to reading a car's MOT history before you go to view it.

Which Suzuki Alto year has the best MOT record?

How these figures are calculated

Source: DVSA Anonymised MOT tests and results, 2025 release. We count first tests of cars and small vans (class 4) aged 3 to 20, so a car that fails and is retested is counted once. A failure includes faults fixed and passed within the same visit. The same age average weights the national failure rate for each age by how many Suzuki Alto cars of that age were tested, so a model is never penalised for having an older fleet. Make and model are as recorded at the test; trim levels are combined. Full method and rankings.
