Used car test drive checklist for South African buyers

A short drive around the block is not enough to judge a used car. A useful test drive starts before the engine is warm, covers different road conditions, and ends with a second inspection after the car has been driven.

This checklist helps you collect evidence. It does not replace an independent mechanical inspection or a formal roadworthy test. A roadworthy test is a safety assessment, not a complete report on the vehicle's mechanical condition.

Before arranging the drive, work through the private-seller buying process and the broader used-car buying checklist.

Before you arrive

Ask the seller not to start or warm the car before you get there. Some noises, smoke and starting problems are easier to spot when the engine is cold.

Bring your driving licence and confirm that the seller is comfortable with you driving the car. Plan a route that includes:

• Stop-start traffic.
• A rougher road or speed bumps.
• A safe section where you can reach normal urban or highway speed.
• An incline for checking clutch, gearbox and engine response.
• A safe place to park and inspect the car again.

If the car is not licensed, insured for the drive, or safe to operate, do not drive it on a public road. Arrange a professional inspection instead.

Before moving, adjust the seat and mirrors, locate the demister and hazard switch, and confirm that no tyre is visibly flat or damaged. Switch the radio off. Ask the seller to sit in the passenger seat if they prefer, but do not let conversation distract you from the vehicle or road.

Use the same route and notes when comparing shortlisted cars. Memory is unreliable after several viewings; a repeatable checklist makes differences easier to see.

Start with the engine cold

Turn the ignition on before starting. The oil-pressure, battery, airbag, ABS and engine warning lights should illuminate as part of the normal self-check, then switch off after the engine starts. A warning light that never appears may deserve as much attention as one that stays on.

Listen during the first start. Repeated cranking, heavy knocking, rattling that does not settle, or clouds of smoke need investigation. A little vapour on a cold morning can be normal, but persistent blue, black or dense white smoke is a reason to pause.

Let the engine idle while you test the lights, indicators, windows, air conditioning, locks, infotainment and dashboard controls. Watch for an unstable idle or a temperature gauge that begins climbing unusually quickly.

Check steering, suspension and brakes at low speed

Begin slowly in a quiet area. Turn the steering from side to side and listen for knocking, clicking or groaning. The wheel should move smoothly and return naturally after a corner.

Drive over a speed bump at a sensible speed. Clunks, repeated bouncing or a car that sits lower on one corner can point to suspension wear. A professional should confirm the cause because tyres, bushes, shocks and alignment can produce similar symptoms.

Test the brakes where it is safe and legal to do so. The pedal should feel consistent, and the car should stop in a straight line without strong vibration through the pedal or steering wheel. Do not attempt an emergency stop in traffic simply to test the vehicle.

Test the clutch or automatic gearbox

In a manual car, check that the clutch engages predictably and that the engine speed does not rise without a matching increase in road speed. Difficulty selecting gears, grinding, a very high bite point or shudder when moving off all deserve closer inspection.

In an automatic, drive from cold and after the vehicle has warmed up. Changes between park, reverse and drive should not produce a long delay or a violent thump. During the drive, watch for slipping, hesitation or harsh changes under gentle and moderate acceleration.

One symptom does not diagnose a gearbox. Record when it happened, at what speed, and whether the car was cold or warm so an inspector can reproduce it.

For an electric or hybrid vehicle, note the displayed charge, estimated range, warning messages and the change in range during the route. Battery health cannot be established from one short drive, so request the relevant diagnostic or battery-health evidence before treating the display as proof.

Drive at normal road speed

On a safe, legal stretch of road, check whether the vehicle tracks straight and whether vibration appears through the seat or steering wheel. Notice wind noise, wheel-bearing hums and changes in sound as you accelerate, cruise and lift off the throttle.

The engine should deliver power consistently without hesitation, warning lights or a rising temperature gauge. Look in the mirror after accelerating: smoke that appears under load can be easier to see from behind than from the driver's seat.

Use all gears and test cruise control if fitted. Confirm that the speedometer and other instruments behave normally. Keep your attention on the road; a passenger can record observations.

Park, restart and inspect again

After the drive, park on a clean, level surface and let the car idle briefly. Look underneath for fresh drips. Switch the engine off, wait a moment, and restart it while warm.

Open the bonnet only when it is safe. Do not open a hot cooling system. Check for new smells, smoke, fluid spray or sounds that were not present before the drive.

Walk around the car again. Uneven tyre wear, hot-brake smells from one wheel, or a wheel that seems much hotter than the others can help an inspector narrow the problem. Do not touch hot brake or exhaust components.

Questions to answer before making an offer

• Did the car start cleanly from cold and again when warm?
• Did every warning light complete its normal self-check?
• Did the steering remain straight and predictable?
• Did the brakes feel consistent without pulling or vibration?
• Did the engine temperature remain stable?
• Did the clutch or gearbox behave well when cold and warm?
• Did you test every feature that matters to you?
• Is the seller willing to allow an independent inspection?

If any answer is uncertain, do not let the viewing turn into a rushed purchase. Take photos or notes, price the likely work, and arrange an inspection before negotiating.

Roadworthy is not the same as a pre-purchase inspection

The South African Government says a vehicle must be tested for roadworthiness before it is registered in a new owner's name. The test covers safety-related items, but it does not tell you whether the car is good value or predict future repairs.

A pre-purchase inspection can go further by checking mechanical condition, diagnostics, repair quality and the specific concerns you recorded during the drive. Read what a pre-purchase inspection should include before choosing a service.

Get a second set of eyes

If you are not confident interpreting a noise, warning light or repair, ask an E-Moto agent to inspect the car and document the findings before you pay. Use the report to decide whether to walk away, request repairs or make an evidence-based offer.
