Smart City Cabriolet

What fails its inspection

Great Britain's MOT record for the 2004 petrol. 54 of 209 tests failed, 26%.

Better than 64% of 2004 cars. The typical one fails 28%, across 750 models with enough tests behind them to say.

The defects inspectors cite

• Windscreen washers not working or not providing sufficient fluid to clear the windscreen
• The aim of a headlamp is not within limits laid down in the requirements
• Lambda coefficient outside the default limits or the range specified by the manufacturer
• Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning
• Emissions levels exceed default limits
• Tyre tread depth not in accordance with the requirements

Where it stands out against its peers

• Exhaust and emissions: failed more often than 93% of 2004 cars — 37% of its 54 failed tests, where an ordinary 2004 car has 15%.
• Visibility: failed more often than 98% of 2004 cars — 35% of its 54 failed tests, where an ordinary 2004 car has 9%.

Same model year only, at least 30 peer cars, zeros included. Every car has a worst part; this shows which, and how far from ordinary it is. A high share means more to check, not a verdict.

NHTSA's investigations are American; no European regulator publishes an equivalent record, so this section has nothing to draw on for a European car. There is no European equivalent of the service-bulletin register either.

• Exhaust and emissions — 37% of its failures
  • Lambda coefficient outside the default limits or the range specified by the manufacturer
  • Emissions levels exceed default limits
  • Exhaust system leaking or insecure
• Brakes — 28% of its failures
• Lights and electrics — 52% of its failures
  • Stop lamp missing, inoperative or in the case of a multiple light source more than 1/2 not functioning
• Visibility — 35% of its failures
  • Windscreen washers not working or not providing sufficient fluid to clear the windscreen
• Body and structure — 22% of its failures

When it starts failing

At 80–100k miles this one fails 23% of its inspections, against the 28% an ordinary car of the same age fails.

163 British inspections, grouped by the odometer reading recorded at the test.

Half of these have more than 60k miles on them. That is how far people drive this car, not how long it lasts.
