The Complete Used Car Buyer's Inspection Checklist
Buying a used car can save you thousands of dollars, but only if you know what to look for. This practical inspection checklist helps you identify hidden issues, review the vehicle's history and buy with confidence.
A used car may look fantastic on the surface, but expensive mechanical problems, accident repairs or outstanding finance can quickly turn a great deal into an expensive mistake. Whether you're buying privately or from a dealer, spending an extra hour inspecting the vehicle could save you thousands in repairs. This guide walks you through everything you should inspect before handing over your money.

Before You Leave Home
A little preparation makes inspecting a used car much easier. Research the vehicle's market value, known issues and common faults before you arrive. Arrange to inspect the vehicle during daylight and avoid buying in the rain if possible.
Preparation Checklist
- Research the make and model.
- Compare asking prices.
- Check common faults online.
- Bring a torch.
- Bring a tyre tread gauge (optional).
- Take your phone for photos.
- Arrange a daytime inspection.
- Allow at least one hour.
Buyer's Tip
If the seller refuses a proper inspection or won't allow a test drive, it's usually worth walking away.
Start With a Walk Around
Before opening the bonnet, simply walk around the vehicle. Look for uneven panel gaps, paint colour differences, obvious repairs or signs the vehicle has been involved in an accident.
Uneven gaps may indicate previous accident repairs.
Different shades can suggest panels have been repainted.
Inspect door sills, wheel arches and around the windscreen.
Body & Paintwork
Cosmetic scratches are normal on older vehicles, but significant repairs may reduce value and indicate previous collision damage.
Inspect Carefully
- Bonnet.
- Roof.
- Doors.
- Bumpers.
- Wheel arches.
- Stone chips.
- Dents.
- Rust.
- Glass chips.
- Headlights.
Tyres & Suspension
Tyres reveal a surprising amount about how a vehicle has been maintained. Uneven tyre wear can indicate poor wheel alignment or suspension issues.
Check For
Tyre age, tread depth, uneven wear, damaged wheels, leaking shock absorbers and suspension noises.
Engine Bay Inspection
The engine is one of the most expensive parts of any vehicle. While modern engines are generally reliable, poor maintenance or neglected servicing can lead to costly repairs. Always inspect the engine before the vehicle has been driven. A cold engine tells you much more than one that's already warm.
Oil Leaks
Inspect underneath the engine and around seals for fresh oil leaks or heavy build-up of grime.
Engine Oil
Check the oil level and colour. Milky oil may indicate coolant contamination.
Coolant
Coolant should be clean and at the correct level with no signs of rust or contamination.
Belts & Hoses
Inspect belts for cracking and hoses for swelling or deterioration.
Battery
Look for corrosion around terminals and check the battery age if possible.
Smoke
Blue, white or excessive black smoke can indicate underlying mechanical problems.
Buyer's Tip
Ask the seller not to start the vehicle before you arrive. A genuine cold start can reveal hard starting, noisy timing chains or excessive exhaust smoke that may disappear once the engine warms up.
Interior Inspection
The interior tells a story about how the vehicle has been treated. Excessive wear may not match the indicated kilometres.
Check for excessive wear, tears and broken adjustment mechanisms.
Heavy wear may suggest higher kilometres than advertised.
Compare pedal wear with the vehicle's odometer reading.
Ensure no warning lights remain illuminated after starting.
Test both heating and cooling functions.
Operate every window, mirror and central locking function.
Technology & Safety Features
Modern vehicles include a wide range of electronics that can be expensive to repair if faulty.

- Touchscreen.
- Bluetooth connectivity.
- Reverse camera.
- Parking sensors.
- Cruise control.
- Steering wheel controls.

Vehicle History & Documentation
Never rely solely on the appearance of the vehicle. Confirm its history before committing to the purchase.
Documentation Checklist
- VIN matches registration.
- Engine number matches records.
- Service history supplied.
- Registration papers.
- Owner's manuals.
- Two keys (where applicable).
- Receipts for major repairs.
- PPSR check completed.
Take It For A Test Drive
A proper test drive is one of the most important parts of buying a used car. Drive on both local roads and higher-speed roads if possible.
During Your Test Drive Check:
Steering feel, braking performance, suspension noises, engine acceleration, transmission operation, clutch engagement (manual vehicles), vibration, wheel alignment and unusual sounds.
