Advisories to look for in a Saab 9-3'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 Saab 9-3, per 1,000 tests. If the car you are looking at has one of these, ask whether it has been fixed since.

  • Tread depth: worn close to legal limit/worn on edge269.7
  • Brake discs: worn, pitted or scored, but not seriously weakened187.0
  • Sub-frame: corroded but not seriously weakened157.0
  • Tyres: slightly damaged/cracking or perishing139.7
  • Engine oil leaks: leak, but not excessive137.6
  • Suspension arms: pin or bush worn but not resulting in excessive movement98.1

Checking a used Saab 9-3 before you buy

The Saab 9-3 has no part of the car that fails well above average for its age, so check the areas that fail most often overall.

  • Suspension

    Drive over speed bumps with the radio off and listen for knocks. Look at the car side on: a corner sitting lower than the others often means a broken coil spring.

  • 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.

  • Brakes

    Look through the wheel spokes at the discs for a deep lip or scoring, check the handbrake holds the car on a slope, and feel for a pull to one side when braking hard.

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.

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 Saab 9-3 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.
