Car mileage check: when high mileage is a problem
High mileage is not automatically bad, and low mileage is not automatically safe. The risk depends on what the car is, how it was serviced and what usually wears at that mileage.

Guide
What to check
Learn why car mileage depends on model, engine, age, service history and known wear points, not only the number on the advert.
Mileage needs context
A diesel used on long motorway trips can age differently from a small petrol used for short urban journeys. Model, engine and service evidence matter.
What changes with mileage
As mileage rises, buyer checks shift toward maintenance proof, suspension wear, clutch and gearbox behaviour, cooling systems, emissions equipment and model-specific weak points.
Evidence matters more than optimism
A high-mileage car with strong invoices can be a better buy than a lower-mileage car with missing history. Duewise treats missing proof as buyer risk.
