Listen for a blowing exhaust at start-up and look underneath for oil or fluid leaks.Suspension: 5.6% of tests fail on suspension, against 4.5% for a typical car of the same age and mileage. Listen for knocks over speed bumps and push each corner down: it should settle at once.Lights: 13.1% of tests fail on lights & electrics, against 6.9% for a typical car of the same age and mileage. Walk round the car with every light on, including brake, fog and number plate lights.Tyres: 5.5% of tests fail on tyres, against 6.1% for a typical car of the same age and mileage. Check the tread on every tyre, including the inner edge, and look for cuts or bulges.Brakes: 4.9% of tests fail on brakes, against 4.3% for a typical car of the same age and mileage.
