Looking to buy a second-hand car? A test drive is essential in the buying process, offering more than just testing the driving experience, it's a chance to inspect the vehicle for issues so you know what you're buying into. Try not to get carried away by the excitement of a potential new car and follow this checklist to make sure you check for all potential issues.
Arrange a cold test drive to inspect fluid levels like coolant, brake fluid, and oil before making a decision.
Checks to complete before getting behind the wheel:
Conduct a thorough check around the car:
- Look for rust around the underside, wheel arches, and sill edges, as it may weaken the car's structure.
- Inspect the bodywork for any dents.
- Examine the exhaust pipe for correct support and condition.
- Check the colour of emissions; blue smoke may indicate oil burning, while black smoke is common in diesel cars.
- Ensure all lights and indicators are functional.
- Verify the condition and proper functioning of seatbelts.
- Inspect the tyres for wear, especially on the inner edges.
- Assess the feasibility of mileage for the car's age, watching for odometer tampering.
- Test the functionality of electrics, including windows, heaters, air conditioning, mirrors, central locking, wipers, and horn.
Inspect under the bonnet:
- Assess the engine's care by checking oil levels; new, golden oil suggests recent servicing.
- Look for leaks or build-up; a yellow-mustard colour inside the oil filler cap may indicate head gasket issues.
- Examine the water expansion tank for clear, coloured water; particles may signal early head gasket failure.
Request paperwork:
- Ask for the V5C and MOT Certificates.
- Check previous MOT advisories for insights into potential future issues.
- Review the log book to verify the service history.
Things to consider before you test drive:
- Before starting the engine, try to avoid distractions from the seller and anyone else viewing the car with you and pay attention to how the car drives and sounds.
- Turn off the radio to detect unusual sounds, like squeaking from the engine, indicating potential issues.
- Check if the engine starts easily from cold, as difficulty may signal battery, alternator, or starter motor problems.
- Monitor warning lights, ensuring they switch off after starting the engine and observing any that come on while driving.
- Verify the normal movement of the speedometer and rev counter.
Things to look out for during a test drive:
- Check acceleration and ensure it meets expectations.
- Assess smooth steering with little effort; detect drifting, which may indicate tyre or suspension issues.
- Turn the wheel 'full lock' to listen for unusual noises, signalling potential power steering or suspension problems.
- Monitor the temperature gauge to avoid overheating issues; let the car idle after the test drive.
- In a manual car, check for easy clutch engagement, smooth gear changes, and proper gearlever 'self-centering.'
- Assess braking effectiveness, listening for any unusual sounds or drifting.
- Test the handbrake on a hill to ensure its effectiveness.
- Drive over speed bumps to evaluate the car's handling on uneven surfaces, listening for unusual knocks and clunks.
After the test drive:
- After the test drive, wait a few minutes and then attempt to restart the car with a hot engine. Difficulty starting can lead to costly issues.
- Did the car offer a comfortable driving experience? Is it a good fit for you and your family? Consider the boot size – is it sufficiently spacious? And is the back-seat area roomy enough?
