Buying a used car can be a great way to save money while still getting a reliable vehicle. However, if you don’t do your due diligence, you could end up with unexpected repair costs or a car that doesn’t suit your needs. Whether you’re purchasing from a private seller or a dealership, it’s important to perform a thorough inspection. Here’s a detailed checklist of ten crucial things to check before buying a used car to ensure you make a smart investment.

1. Vehicle History Report: Know the Car’s Past
Before committing to a used car, always check its history report. This report provides essential details about the vehicle’s past, including previous owners, accident history, and service records. In Australia, services like PPSR (Personal Property Securities Register), CarHistory, and Got It Motors offer detailed reports.
Why It’s Important:
- Accident History: A car involved in major accidents may have structural weaknesses.
- Outstanding Finance: If the previous owner hasn’t settled the car loan, it can be repossessed.
- Odometer Tampering: A history check helps identify discrepancies in mileage records.
A vehicle with a clean history report is generally a safer purchase, but if the report reveals concerns, it’s best to reconsider or negotiate the price accordingly.
2. Exterior and Interior Condition: Check for Visible Damage
A visual inspection can reveal a lot about a used car’s condition. Start by examining the exterior for signs of damage, rust, dents, or mismatched paint, which could indicate previous repairs.
What to Inspect:
- Exterior: Look for scratches, rust spots, and panel gaps that suggest previous repairs.
- Windscreens & Windows: Check for chips or cracks.
- Tires & Wheels: Uneven tire wear may indicate alignment issues.
- Interior: Inspect the upholstery, dashboard, and controls for signs of wear and tear.
A well-maintained interior and exterior suggest the car has been cared for properly. If the car has excessive wear, consider how much additional money you may need for repairs.

3. Engine and Transmission: Assess Performance
The engine and transmission are the heart of any vehicle. A problematic engine can lead to costly repairs, so a thorough check is necessary.
Key Checks:
- Oil Condition: Dark, sludgy oil may indicate poor maintenance.
- Leaks: Check under the car for oil, coolant, or transmission fluid leaks.
- Noises: Unusual knocking or ticking sounds may signal engine trouble.
- Transmission: Make sure the gear shifts smoothly in both manual and automatic cars.
A test drive (discussed later) is crucial to properly assess the engine and transmission performance.
4. Odometer Reading: Verify the Mileage
Odometer readings help determine how much a car has been used. In Australia, the average car travels around 13,000 to 15,000 km per year. If the reading seems too low or too high for the car’s age, be cautious.
Red Flags:
- Excessive wear on the pedals, steering wheel, or seats despite a low mileage.
- A history report that shows mileage inconsistencies.
- No service records to support the mileage claims.
Low mileage is not always a good thing if the car has been sitting idle for long periods, as this can lead to mechanical issues.
5. Brakes and Suspension: Ensure Safety on the Road
Brakes and suspension directly impact the safety and comfort of your drive.
What to Check:
- Brakes: Press the brake pedal; if it feels spongy or the car pulls to one side, it may indicate worn-out brakes.
- Suspension: Push down on each corner of the car; if it bounces excessively, the shocks may be worn.
- Steering Response: If the steering feels loose or vibrates, it may need repairs.
A mechanic’s inspection can give you a clearer picture of the vehicle’s braking and suspension health.
6. Electrical Components: Test All Features
Modern cars have numerous electrical components, from headlights to infotainment systems. Testing these ensures everything is in working order.
Essential Electrical Checks:
- Headlights, Indicators & Brake Lights: Ensure all exterior lights function correctly.
- Air Conditioning & Heating: Check for proper temperature control.
- Power Windows & Locks: Test all doors and windows.
- Infotainment System: Ensure the radio, Bluetooth, and other features work.
Electrical faults can be costly to repair, so testing these features beforehand can save future headaches.
7. Service and Maintenance Records: Evaluate Previous Care
A well-documented service history indicates a properly maintained car. Look for service records that show regular oil changes, brake pad replacements, and major servicing milestones.
What to Look For:
- Consistent Maintenance: Regular servicing intervals (every 10,000–15,000 km) show responsible ownership.
- Timing Belt Replacement: For cars over 100,000 km, check if the timing belt has been changed.
- Logbooks & Receipts: Having these records adds value and transparency to the purchase.
If there are missing records or gaps in servicing, consider getting the car inspected by a professional mechanic.
8. Fuel Efficiency: Know the Running Costs
Fuel efficiency can make a significant difference in long-term running costs. In Australia, fuel prices fluctuate, so buying a fuel-efficient car can save you money.
General Fuel Efficiency Guide:
- Small Hatchbacks: 5-7L per 100 km
- Sedans: 7-10L per 100 km
- SUVs & Utes: 9-15L per 100 km
Check online reviews or manufacturer specifications to see if the car’s fuel economy matches your expectations.
9. Registration and Insurance: Avoid Legal Issues
Before purchasing, confirm that the car’s registration is valid and that no outstanding issues exist.
Key Documents to Verify:
- Registration Papers: Ensure they match the seller’s details.
- PPSR Check: Confirms the car isn’t stolen or under finance.
- Insurance Costs: Research insurance rates for the model before buying.
Failing to check registration and ownership details could result in unexpected legal troubles.
10. Test Drive: The Final and Most Important Step
A test drive is essential to evaluate the car’s real-world performance. It helps identify potential mechanical problems that aren’t obvious in a visual inspection.
Things to Observe:
- Engine Noise: Listen for rattling, knocking, or excessive noise.
- Acceleration & Braking: Ensure smooth performance in both aspects.
- Steering & Handling: The car should respond quickly without vibrations.
- Comfort: Check for wind noise, vibrations, and seat comfort.
If anything feels off during the drive, it’s best to get a mechanic’s opinion before making a final decision.
Conclusion: Make a Smart and Informed Purchase
Buying a used car requires thorough inspection and research. By following this checklist, you can avoid costly mistakes and drive away with a reliable vehicle. Always check the history report, inspect the car inside and out, verify mileage and service records, and take it for a test drive. If in doubt, consulting a trusted mechanic can save you from future problems.
