What do those numbers on the odometer mean? We’re looking at what car mileage tells you, and what else to look for when assessing the condition of a used car.
The average South African drives approximately 21 000 km per year, yet most car buyers still consider mileage as a mystical number that determines a vehicle’s entire worth.
According to NerdWallet research, correctly understanding car mileage (the highest kilometre reading on the odometer in the centre of the instrument cluster) can save you thousands when buying used cars.
The truth is, mileage (shown above by the number 222 199) tells only part of the story. A well-maintained vehicle with 150 000 km can outlast a neglected car with half that distance.
Smart buyers know that context matters more than numbers on the odometer, and the real secret lies in understanding what those kilometres truly represent about a car’s life story.

What Counts as Good Car Mileage?
Good mileage for a used car is typically under 19 000 km per year for petrol vehicles and under 16 000 km annually for turbodiesel cars.
This benchmark gives you a starting point, but the story gets even more interesting. Modern vehicles are built to last well beyond 160 000 km, with many reaching 320 000 km or more through proper care. The magic number isn’t the total distance – it’s how those kilometres are accumulated.
A car that racked up highway kilometres during long commutes will typically show less wear than one that spent years navigating stop-and-go city traffic. Highway driving is gentler on brakes, transmission, and engine components. City driving creates more stress through constant acceleration and braking.

How Vehicle Type Affects Mileage Standards
Different vehicles handle high mileage differently. SUVs and trucks often see higher annual mileage due to their intended use for longer trips and heavier work. These vehicles are typically built with more robust components to handle demanding conditions.
Luxury vehicles might seem concerning with higher mileage, but some premium car brands, such as Honda and Lexus, are engineered for longevity. Their higher initial cost often reflects superior build quality that pays dividends over time. Meanwhile, economy cars can surprise you with their durability when maintained properly; Toyota and Suzuki have built reputations on exactly this reliability.

What Affects Car Durability?
Maintenance Matters Most
The difference between a car that suffers a catastrophic mechanical failure at 100 000 km and one that runs highly reliably after 250 000 km usually comes down to maintenance. Regular oil changes, filter replacements, and scheduled servicing prevent small problems from becoming expensive failures.
Service records tell the real story of a car’s health. A vehicle with complete maintenance documentation often proves more reliable than a low-mileage car with no service history. Smart sellers keep these records because they know informed buyers will pay more for transparency.
Driving Habits Leave Their Mark
How previous owners drove matters enormously. Aggressive driving, which includes rapid acceleration, hard braking, and poor shifting technique, accelerates wear on every component. These habits stress the engine, transmission, brakes, and suspension systems.
Conversely, gentle driving extends component life significantly. Cars driven by cautious owners often perform well beyond expected lifespans. (Which is why many dealers advertise vehicles with the words, “previous lady owner.”) Unfortunately, you can’t always determine driving style from appearance alone, which makes professional inspections valuable.
Environmental Challenges
South Africa’s diverse climate creates unique challenges for vehicles. Coastal areas expose cars to salt air that accelerates corrosion (rust). Inland regions face extreme temperature swings that stress cooling systems and batteries. Gauteng’s high altitude affects engine performance and fuel efficiency.
Road conditions vary dramatically across the country. Potholes and rough surfaces damage suspension components and alignment. Rural areas might mean more dust and debris, while urban environments create different wear patterns through constant stopping and starting.

Smart Used Car Shopping Strategy
With knowledge about what affects car durability, you can approach used-car shopping with confidence. The key is developing a systematic approach that weighs mileage alongside other critical factors.
Calculate Annual Mileage First
Take the total mileage and divide by the car’s age. This simple calculation reveals usage patterns immediately. A 5-year-old car with 120 000 km averages 24 000 km annually, which is higher than ideal but not necessarily problematic if other factors align.
Compare this figure against the benchmarks, but remember that 1 high-mileage year doesn’t doom a vehicle. Maybe the previous owner took a long road trip or had a job that required extensive travelling.
Look Beyond the Numbers
Mileage provides context, not conclusions. A complete evaluation includes maintenance records, visual inspection, and professional assessment. Check for signs of wear that don’t match the odometer reading – excessive pedal wear, steering wheel shine, or seat deterioration might indicate problems.
Vehicle history reports reveal accidents, repairs, and registration changes that affect value and reliability. Multiple previous owners or commercial use can impact longevity regardless of mileage.

A Professional Inspection Is Worth The Price
Even experienced car enthusiasts benefit from professional inspections. Qualified mechanics spot issues that escape casual observation. They can assess engine condition, transmission health, and structural integrity beyond what mileage alone suggests.
This investment often saves a buyer money by identifying problems before purchase or providing negotiation leverage. A clean inspection report also gives peace of mind that your mileage assessment was accurate.

Red Flags to Watch
Extremely low mileage on older cars can indicate prolonged storage, which creates problems of its own… Seals dry out, fluids degrade, and components seize from lack of use. These cars might need extensive work despite appearing pristine.
Conversely, suspiciously high mileage might indicate commercial use, fleet service, or ride-sharing history. These applications create different wear patterns and stress levels compared to personal use.
Making Your Decision
Good mileage varies by vehicle type, intended use, and personal circumstances. A car with 100 000 km might be perfect for someone needing reliable transportation for several years, while another buyer might prefer lower mileage for long-term ownership.
Consider your own driving patterns and maintenance commitment. High-mileage vehicles often require more frequent attention and repairs. Budget accordingly and choose vehicles known for reliability in their higher-mileage years.

Your Next Step Forward
Understanding mileage helps you make informed decisions, but it’s just 1 piece of the used-car puzzle.
The best approach combines mileage analysis with thorough research, professional inspection, and realistic expectations about any vehicle’s future needs. Knowing how your potential purchase fits the general South African mileage pattern gives you negotiating power and confidence in your choice.
