The most common advisory or minor defect: tread depth: worn close to legal limit/worn on edge, on 6.5 per 100 MOTs.

Problems by part at 5 years

Repair estimates are a guide for an independent garage: labour at the national median local garage rate (median £78 an hour from 65 garages, ONS price quotes) times estimated labour hours, plus a parts band. Labour hours and most parts bands are estimates, not quotes, and prices vary by model, engine and region. A warning light fault shows the cost of the diagnosis only.

What to check on a viewing

On the Bentley Bentayga, testers most often record tyre condition: has a cut in excess of the requirements deep enough to reach the ply or cords. Look at these first, then the areas below.

Tyres

Check the tread across the full width of all four tyres, and the spare if there is one.
Look for cuts, bulges and cracking in the sidewalls.
Wear on one edge only can point to worn suspension or the tracking being out.

Lights and electrics

With someone outside, try every light: dipped and main beam, indicators, brake lights, fog lights and number plate lamps.
Check that the warning lights come on with the ignition and go out once the engine runs.
Look for misted, cracked or yellowed headlamp lenses.

Exhaust, emissions and leaks

Start the engine from cold if you can and watch the exhaust for blue or black smoke.
Check that the engine warning light goes out after starting and stays out on the test drive.
Look under the car and around the engine for oil or fluid leaks, and listen for a blowing exhaust.

Ask for the car's MOT history and service record: advisories that repeat from one year to the next show what has been left. GOV.UK MOT history.

Read this with care. A fail rate is not a measure of build quality. How far cars are driven, how they are used and how well owners maintain them all change it, and wear items such as tyres and brake pads are common fails. Compare a model only with cars of the same age. Methodology and limits.

The all cars figures cover all class 4 vehicles (cars and light vans) tested at the same age.
