The complete used car buying checklist for Australia (2026)

Why you need a checklist

Buying a used car is one of the largest purchases most Australians make outside of property. The average transaction price for a used vehicle in Australia sits between $20,000 and $30,000, and unlike buying from a retailer, there is no universal return policy. Once you hand over the money, unwinding a bad purchase is expensive, stressful, and sometimes impossible.

The difference between a good used car purchase and a bad one almost always comes down to preparation. Buyers who follow a structured process — research first, check the history, inspect thoroughly, negotiate with data — consistently get better outcomes than those who buy on impulse.

This checklist covers every step from the moment you start looking to the moment you drive away. It applies whether you are buying from a private seller or a dealer, and whether you are shopping on Facebook Marketplace, Carsales, Gumtree, or a dealer lot.

Step 1: Research before you shop

Most buying mistakes happen because the buyer skipped the research phase. Before you look at a single listing, get clear on what you need and what you can afford.

• Set your total budget — not just the purchase price. Factor in stamp duty, registration transfer, insurance, servicing, and any immediate repairs. A $15,000 car can easily cost $17,000–$18,000 by the time you drive it home.
• Shortlist 2–3 models — research reliability ratings, common faults, and running costs for each. Owner forums are often more honest than review sites.
• Learn the market price — check listings on Carsales, Facebook Marketplace, and Gumtree to understand what your target car sells for in your area. A market valuation from Glass’s Guide or RedBook gives you a benchmark. RegoVerify Full Reports include a Glass’s Guide valuation for $14.99.
• Decide private or dealer — private sales are typically 10–20% cheaper but come with no statutory warranty. Dealers must provide consumer guarantees under Australian Consumer Law. Read our private sale vs dealer guide to weigh the tradeoffs.
• Arrange finance first — if you need a loan, get pre-approval before you start shopping. Pre-approval gives you a firm budget, stronger negotiating power, and protection against dealer finance upselling.

Step 2: Run a vehicle history check

This is the single most important step and the one most buyers skip or leave until too late. A vehicle history check should be the first thing you do after finding a listing you like — before you arrange an inspection, before you test drive, and well before you hand over any money.

A comprehensive vehicle history report will tell you:

• Write-off status — whether the vehicle has been declared a statutory or repairable write-off in any Australian state or territory
• Finance owing — whether any lender holds a security interest registered on the PPSR. If you buy a car with finance owing, the lender can repossess it from you.
• Stolen vehicle flag — whether the vehicle has been reported stolen through police databases
• Safety recalls — whether there are any outstanding manufacturer recalls, including the critical Takata airbag recall
• Market valuation — what the vehicle is actually worth based on Glass’s Guide data (Full Report only)

Step 3: Inspect the vehicle in person

Photos lie. Even video calls miss details. There is no substitute for seeing the car in person, in daylight, on a dry day. Inspect the car when the engine is cold — a warm engine can mask starting problems and unusual noises.

Exterior check

• Walk around the car and look along each panel at eye level. Ripples or colour mismatches indicate previous repair work or write-off repair.
• Check panel gaps — uneven gaps between doors, bonnet, and boot lid suggest crash damage or poor repairs.
• Inspect all four tyres. Uneven wear patterns can indicate alignment issues or suspension problems. Check the tread depth — replacing four tyres costs $400–$1,200 depending on the vehicle.
• Look under the car for oil leaks, rust on the exhaust or subframe, and any signs of fluid dripping.
• Check all glass for chips and cracks. Windscreen replacement costs $300–$800.

Engine bay

• Check the oil level and condition. Dark, gritty oil suggests missed services. Milky residue on the oil cap can indicate a head gasket issue.
• Check coolant level and colour. It should be bright (green, pink, or blue depending on the type). Brown or rusty coolant means the system has not been maintained.
• Look for corrosion on battery terminals and check the age of the battery. Most car batteries last 3–5 years.
• Inspect belts and hoses for cracking, perishing, or loose connections.

Interior and electrics

• Check every electrical function: air conditioning (both hot and cold), all windows, mirrors, central locking, infotainment system, Bluetooth, reversing camera, and parking sensors.
• Test all lights: headlights (low and high beam), indicators, brake lights, fog lights, and interior lights.
• Check the dashboard for warning lights. Turn the ignition to the “on” position (without starting the engine) — all warning lights should illuminate briefly, then go off. If the check engine or airbag light stays on, there is a fault.
• Smell the interior. Musty or mouldy smells suggest water damage. Strong air freshener can be masking something.
• Check seat condition, carpet wear, and pedal rubber wear. These should be consistent with the claimed odometer reading. Heavily worn pedals on a car claiming low kilometres is a red flag for odometer tampering.

Step 4: Test drive

A test drive is not a joyride. You are testing the vehicle for faults, and that means driving in a variety of conditions. Plan a route that includes suburban streets, a stretch of highway, some hills, and a few speed bumps.

• Cold start — listen to the engine when first starting. Rattling, knocking, or excessive smoke from the exhaust on start-up are warning signs. Blue smoke means burning oil. White smoke (other than brief condensation in cold weather) can indicate a head gasket issue.
• Transmission — for automatic, check for smooth shifting through all gears. Hesitation, jerking, or slipping between gears means expensive repairs. For manual, check the clutch biting point — if it engages very high, the clutch is worn.
• Brakes — test at various speeds. The car should stop straight without pulling to one side. Listen for squealing or grinding. A pulsating brake pedal suggests warped rotors.
• Steering — on a straight, flat road, briefly loosen your grip on the steering wheel. The car should track straight. Pulling to one side indicates alignment or suspension issues.
• Suspension — drive over speed bumps and listen for clunks, rattles, or banging from the underside. Excessive bouncing after bumps means worn shock absorbers.
• Highway — take the car to 100 km/h if safe. Listen for wind noise, vibrations through the steering wheel or seats, and any unusual sounds that only appear at speed.

Step 5: Verify the VIN, rego, and seller identity

Before you commit to buying, verify that the car is what it claims to be and that the seller has the right to sell it. This step protects you from vehicle rebirthing, fraud, and buying stolen property.

• Check the VIN in three places — the compliance plate (usually on the firewall or door jamb), the dashboard plate (visible through the windscreen), and the engine bay stamping. All three must match. If any differ, do not proceed.
• Match the VIN to the registration certificate — the VIN on the physical vehicle must match the VIN on the rego papers and on your vehicle history report.
• Verify the seller’s identity — ask to see their driver’s licence and confirm the name matches the registered owner on the rego certificate. If someone is selling on behalf of the owner, get written authorisation and contact the owner directly.
• Check the odometer matches records — compare the current reading with the reading on service records and your vehicle history report. Significant discrepancies are a sign of odometer tampering.

Step 6: Get a pre-purchase mechanical inspection

A vehicle history check tells you the car’s administrative history. A mechanical inspection tells you its physical condition. You need both.

Book an independent mechanic — not one the seller recommends. Mobile inspection services like those offered by state motoring clubs (RACV, NRMA, RACQ, RAA) will come to the car’s location and provide a detailed written report. This typically costs $200–$350 and covers the engine, transmission, suspension, brakes, steering, electrical systems, body condition, and a road test.

• If the seller refuses to allow a mechanical inspection, walk away immediately. No exceptions.
• Ask the mechanic for a list of any required or recommended repairs, with estimated costs. Use this in your negotiation.
• Pay attention to the “major concern” items. Minor issues like worn brake pads are normal wear. Major issues like engine oil leaks, transmission problems, or structural rust are reasons to walk away or negotiate a significant discount.

Step 7: Negotiate the price

If you have followed the steps above, you now have a vehicle history report, a mechanical inspection report, and a clear understanding of the car’s market value. This puts you in a strong position to negotiate the price.

• Start with the data: show the seller the market valuation and any issues flagged in the inspection or history report. Concrete evidence is more persuasive than general haggling.
• Factor in any repairs the mechanic identified. If the car needs $800 in brake work and new tyres, that should come off the asking price.
• Be prepared to walk away. The best negotiating tool is genuine willingness to leave. There will always be another car.

Step 8: Complete the paperwork

Getting the paperwork right protects both you and the seller. Miss a step and you could face fines, disputes, or problems with insurance.

• Receipt of sale — both parties sign a receipt that includes: buyer and seller full names and addresses, the VIN, registration number, make, model, year, odometer reading, agreed purchase price, date of sale, and payment method.
• Roadworthy / safety certificate — required in most states for used car sales. In Victoria and Queensland the seller must provide a current roadworthy certificate. In NSW and some other states, the buyer arranges it. Check your state’s requirements.
• Registration transfer — lodge the transfer with your state transport authority within 14 days (the timeframe varies by state). You will need to pay stamp duty, which is calculated as a percentage of the purchase price or market value, whichever is higher.
• Payment method — pay by bank transfer for a traceable record. If you must pay in cash, both parties should sign the receipt at the time of payment. Never pay a deposit before seeing the car and completing your checks.
• Insurance — arrange at least CTP (compulsory third party) insurance before driving the car. Comprehensive insurance is strongly recommended — if you crash on the drive home, you are covered.

The bottom line

Buying a used car does not have to be stressful. The buyers who end up with problems are almost always the ones who skipped steps — rushed the decision, did not check the history, or trusted a seller’s word instead of verifying the facts. Follow this checklist from start to finish and you will dramatically reduce your risk of buying a car with hidden write-off damage, outstanding finance, safety recalls, or mechanical problems that cost thousands to fix.

Start with a RegoVerify vehicle history check — it takes 30 seconds and covers PPSR, write-off, stolen, finance, recalls, and valuation data from $4.99.
