Mileage is often seen as a primary indicator of a car’s condition, but the reality is more nuanced. While it does give a general idea of how much a vehicle has been used, it should never be the sole deciding factor. A well-maintained high-mileage car can be a far better purchase than a neglected low-mileage one, and understanding how mileage impacts a car’s wear and value is crucial when making a decision.
Understanding Mileage and Wear
Mileage reflects the distance a car has travelled, but its impact on wear depends on how the car has been driven and maintained. A low-mileage car with fewer than 50,000 miles may seem appealing, but infrequent use can lead to issues such as dried-out seals, corrosion, and a neglected service schedule. On the other hand, a moderately used car with mileage between 50,000 and 100,000 miles often represents the best balance—driven regularly enough to keep everything in working order but not excessively worn out. Cars exceeding 100,000 miles may deter some buyers, but many premium models, especially from well-engineered brands, are built to last well beyond this point if properly cared for.
The Type of Miles Matter
Not all miles are equal. A car that has primarily been used for long-distance motorway journeys will have significantly less wear than one that has spent its life in urban stop-start traffic. Motorway miles put minimal strain on an engine, gearbox, and suspension, allowing for smoother wear over time. In contrast, city driving exposes a car to constant braking, short journeys, and harsher start-up cycles, leading to more stress on mechanical components. Ideally, a used car should have a mix of both, ensuring that it has been used efficiently without excessive wear on key systems.
Manufacturer Differences in Longevity
Some brands and models are engineered to handle higher mileage better than others. German manufacturers like BMW, Mercedes-Benz, and Audi often design their engines and transmissions to last well beyond 150,000 miles, provided they receive regular maintenance. Japanese brands, particularly Lexus, Honda, and Toyota, have a reputation for exceptional longevity, with many well-kept examples reaching 200,000 miles or more. In contrast, high-end luxury brands such as Jaguar, Land Rover, and Maserati can be more delicate, as their complex electronics, air suspension systems, and high-performance components often require expensive repairs as the mileage increases.
Service History is More Important Than Mileage
A car’s service history tells a more accurate story than mileage alone. Regular servicing ensures that vital components such as the engine, gearbox, suspension, and brakes remain in good condition. Full service history, ideally from a main dealer or specialist, is a strong indicator that a car has been properly maintained. Key component replacements, such as timing chains, gearbox oil changes, and suspension refreshes, can extend a car’s life significantly. Cars owned by enthusiasts or meticulous previous owners often receive above-average care, making them a safer choice even at higher mileages.
Does Mileage Affect Resale Value?
Higher-mileage cars typically depreciate faster, but certain premium models hold their value well if they have a solid maintenance record. If resale value is a concern, it’s important to consider how long you intend to keep the car. A low-mileage example may be easier to sell in the future, but if you plan to keep the car for many years, buying a well-maintained higher-mileage model at a lower initial cost can often be the smarter financial decision.
Conclusion: Should You Avoid High Mileage?
Mileage should never be viewed in isolation. A low-mileage car can suffer from long periods of inactivity, while a high-mileage car can still be in excellent condition if properly maintained. Instead of focusing solely on the odometer reading, evaluate the car’s service history, how it has been driven, and the condition of its key components. In many cases, a moderately used, well-cared-for car offers the best balance of reliability, longevity, and value.
