Follow the service schedule
Regular servicing is the foundation of sensible used-car ownership. The exact interval depends on the manufacturer and model, so use the handbook or service information for your car rather than relying on a generic timetable. Keep invoices and records because they can also help when you eventually sell.
Check fluids between services
Engine oil, coolant and screenwash are easy to overlook. Check levels on level ground and follow the manufacturer's instructions. A sudden drop in oil or coolant can be a warning sign that deserves investigation rather than simply topping up repeatedly.
Look after your tyres
Correct tyre pressure helps safety, handling and efficiency. Check pressures when tyres are cold and inspect for cuts, bulges and uneven wear. Uneven wear can point to alignment or suspension issues, so it is worth dealing with the cause rather than only replacing the tyre.
Pay attention to changes
Owners get used to how their car normally sounds and feels. New vibrations, warning lights, fluid smells, pulling under braking or unusual noises should not be ignored. Small problems are often easier and cheaper to diagnose when they first appear.
Keep the car clean
Cleaning is not only cosmetic. Removing salt and dirt from bodywork and wheel arches can help protect surfaces, while a clean interior makes leaks and unusual wear easier to spot. A well-kept car is also much easier to present when it is time to advertise it.
