If you can, ask about the previous owner's profile and how the car was predominantly used. It's not always possible to verify, but it changes the picture.

Make and model reliability matters more than either variable

Here's the thing buyers often overlook: the brand and model is frequently more predictive of long-term durability than the specific odometer reading.

A used Toyota HiLux or used Mazda CX-5 with 180,000km and a complete service history represents a car with a well-documented track record of longevity. The same is not automatically true of a higher-mileage European model with known reliability quirks and patchy records. Some makes handle high kilometres with relatively few problems. Others accumulate expensive issues from the mid-life point onward regardless of how carefully the car was driven.

Research the specific model's common failure points before you commit. Owner forums, independent reviews, and repair cost data are all useful. A car with 50,000 fewer kilometres on a less reliable platform might end up costing more in repairs over your ownership period than one with a longer history on a more durable one.

A car that has sat unused is not automatically a low-risk buy

It seems logical that a car with low kilometres has had an easier life. But there's a difference between low km because the car has been lightly used by a careful owner, and low km because the car has sat idle in a garage or driveway for extended periods.

Cars are built to move. Extended periods of disuse cause specific types of damage. Rubber seals and hoses degrade even without mechanical stress. Brake components can corrode from lack of use. Fuel systems, particularly in older cars, suffer from stale fuel residue and clogged injectors. Batteries lose capacity and tyres develop flat spots.

Should you buy a car with over 100,000km? explores the broader question of what the odometer really signals. The short version: a well-maintained higher-km car is often a sounder buy than a neglected or long-dormant one with a smaller number on the dash.

Service history is the tie-breaker

If you only take one thing from this article, make it this: service history is the most important variable in the km vs age equation.

A newer car with more kilometres and a complete, documented service history is almost always the smarter choice over an older car with fewer km and gaps in its record. The history tells you how the car has been maintained, whether issues have been caught early, and whether the previous owner treated servicing as routine rather than optional.

Gaps in service history raise the question of what was not done, and when. That's the harder risk to price.

For buyers who are not confident assessing whether kilometres are "good" kilometres or not, knowing what was done to the car between services matters enormously. That is where independent inspection matters: at Carma, every car goes through our quality process before it reaches the listing stage, so the mechanical condition is assessed regardless of what the odometer says.

The kilometres aren't the whole story

When you are faced with the choice between a newer car with more km or an older car with fewer km, resist the temptation to pick a winner based on the numbers alone. Look at the km relative to age, understand how those kilometres were likely accumulated, research the model's reliability record, and check the service history carefully.

A car that has been used well and maintained consistently is a better buy than one where the odometer just happens to show a flattering number.

Drive it, don't just count it

The odometer is a starting point, not a verdict. The buyers who consistently get the best value from the used car market are the ones who understand that a newer car with more km or an older car with fewer km can both be excellent choices. It depends on the story behind the numbers.
