Most used-car advice is a list of things to look at. The more useful framing is what each check is actually protecting you from, because that tells you which ones you can skip and which you cannot.
Start with the paperwork, not the car
Everything expensive to get wrong is on paper. Confirm the vehicle identification number on the car matches the documents, in all the places it appears. Check the registration document names the seller. Run a history check for outstanding finance, insurance write-offs, recorded mileage and whether it has been reported stolen.
Outstanding finance is the one that ruins people. If money is owed against the car, the finance company can repossess it after you have paid the seller, and you are left with neither. No physical inspection reveals this.
The inspection that matters
- Look along the panels in daylight. Ripples, mismatched paint texture and inconsistent panel gaps indicate accident repair. Poor repairs hide rust and structural damage.
- Check tyre wear across each tyre. Uneven wear across the tread suggests alignment or suspension problems. Wear differing between sides suggests something bent.
- Cold start it. Insist the engine is cold when you arrive. A warmed-up engine hides starting problems and smoke, and a seller who warmed it up may know that.
- Watch the exhaust on start. Blue smoke means oil burning, white that persists can mean coolant, black means fuelling. All three are expensive.
- Test every electrical item. Windows, mirrors, locks, air conditioning, heated seats. Electrical faults are tedious and costly to trace.
- Check service history against the odometer. Gaps and inconsistencies matter more than the total mileage.
Mileage is not the number people think it is
A high-mileage car driven mostly on long runs and serviced on schedule is usually in better condition than a low-mileage car used for short cold trips. Short journeys are hard on engines, exhausts and batteries because nothing reaches operating temperature.
Judge condition and history first, and treat mileage as one input rather than the headline.
The test drive
Drive it long enough to reach full operating temperature, which is longer than most sellers expect. Include a rough surface to hear the suspension, a stretch at speed to feel for vibration, and full-lock turns in both directions to hear the joints. Brake firmly once, somewhere safe, and feel whether the car pulls to one side.
Turn the radio off for the whole drive. Almost every mechanical warning is a sound.
Common questions
Is an independent inspection worth it? On any car costing real money, yes. It costs a fraction of one significant repair and gives you a negotiating position.
Private seller or dealer? Private is usually cheaper with fewer legal protections; a dealer costs more and owes you more. Which is right depends on how much risk you want to carry.
How much should I hold back for repairs? Assume something will need doing in the first year and budget for it. A used car with no immediate needs is the exception.
Does a full service history guarantee anything? No, but its absence is a reliable warning, and stamps should be checked against the garages that supposedly made them.
