Used car buying guide
If you're buying a used car, follow our simple steps so you don't end up with a lemon.
Looking for pre-loved wheels?
You're in the market for a used car, but you don't want to buy a lemon. You're wondering if it's possible to spend less than you would on a new car, and still get something safe and reliable. It is, but be prepared to do some homework.
We've compiled a step-by-step guide to help you buy a used car that you'll love for years – and kilometres – to come.
Before you buy a used car
Don't rush, take your time and do your research into the different makes and models, and consider the following:
- Your budget. Work out how much you can afford to spend. Red Book will guide you on the value of cars according to their year and model.
- Your needs. What will you use the car for? If you do most of your driving in the city, a four-wheel drive is hardly necessary.
- Safety. Check our used car safety ratings that are based on real-life accidents.
- Security. How easy is it to steal or break into the car? What security features is the car equipped with? Check the NRMA's car security scores.
- Insurance costs. These will vary from model to model. Once you've narrowed down your options get some quotes.
- Environment. Check the car's fuel consumption and emissions rating. The Green Vehicle Guide can help you here.
- Dealer, auction or private sale. Decide where and how you want to buy the car. See what we have to say about these options further down in this article.
- Regulations. Check your state or territory's regulations around buying and selling used cars, including how to make sure there's no money owing on the car. We have more info on this later in this article.
- Inspect the car using the checklist below.
- If you're not comfortable inspecting the car yourself you can organise an independent expert inspection through your state's motoring organisation. If you buy at auction, though, this usually isn't possible.
- If you find a car that fits your criteria, check that it is debt-free. If you buy the car from a dealer, they're legally obliged to guarantee that the car's debt-free. For private sales you can check the national Personal Property Securities Register (PPSR) – this has replaced numerous existing asset registers across Australia, including the Register of Encumbered Vehicles or REVS. Have the vehicle identification number (VIN) or chassis number ready. There is a fee of $3.40 per search payable by Visa, MasterCard or American Express.
- Don't sign until you're completely happy with the car and its cost.
- Ask questions about the vehicle's history – how many owners has the vehicle had previously? Has it been involved in any crashes? What's the mileage? How much does it cost to fill the tank? Is the vehicle currently registered and insured? What safety features does it have?
After the sale
- Arrange insurance once you've bought the car and before you drive it anywhere.
- Transfer the registration to your name. You usually have to do this within a few days of buying the car.
Dealer, auction or private sale?
Buying from a dealer is usually more expensive than buying privately but there are some advantages:
- In some states and under certain conditions, they must provide a statutory warranty. This can often exclude parts like the radio, air conditioning and battery so make sure you're clear on what is and isn't covered.
- They must guarantee there's no money owing on the car.
- They usually have to display a form on the car's dashboard or windscreen that provides some basic information, such as the year of manufacture, odometer reading and warranty details.
- You can trade in your old car.
You might be able to pick up a bargain at auction but you really need to know about cars and what they're worth.
- You usually can't arrange for an inspection or even a test drive.
- You'll be relying purely on visual checks.
- Auctions vary from state to state so you'd need to check with the auction house about warranty and money owing.
Buying a car privately is usually cheaper than buying from a dealer, but you have to rely a lot more on your own judgment as you won't get any protection like statutory warranty.
- Get the car inspected by your state's motoring authority if you're not confident.
- Check if there's any money owing on the car by calling the vehicle title registry or REV's in the state the cars registered in.
Car markets are pretty similar to buying privately. They bring private sellers and buyers to the one place, allowing you to look at a number of different cars without having to drive all over town. You probably won't be able to have the car inspected on the same day but you can usually go for a test drive.
How to inspect a used car
There's a lot to check when you're inspecting a car. It's a good idea to take someone with you, because two sets of eyes are always better than one. Also, go look at the car in full daylight, where marks, dents and other defects are clearly visible. Here's a checklist to help you get through it:
- In a private sale make sure the seller is the owner. Ask to see their driver's licence and compare the details with those on the registration papers.
- Look at the car's compliance plate which is usually found on the firewall between the engine area and the inside of the car.
- Match the VIN number, date of manufacture, engine number (which is marked on the engine itself) and number plates with those on the registration papers. Ask for an explanation if any of the information doesn't match. It could mean that the car's been stolen or that the engine's been replaced without notifying the registration authority.
- Check if you should be receiving a certificate of roadworthiness. The seller is required to provide it in some states.
- Check the paintwork for bubbles and colour differences which could indicate rust or an accident. Use a fridge magnet to check suspicious areas for body filler – the magnet won't stick to filler.
- Panels that don't seem to fit properly, or doors, the boot, lid and windows that don't open and close properly can indicate the car's been in an accident.
- Check the tyres, including the spare, for enough tread (at least 3-4mm) and uneven wear (which can show a problem with the steering or suspension).
- Check under the car for oil leaks.
Under the bonnet
- Look at the dipstick. Grey or milky oil may indicate serious engine problems.
- Take off the radiator cap and check the coolant. It should be brightly coloured and clean. Oil in the coolant may also indicate serious engine problems.
- Check the radiator cooling fans and the battery and its mounting platform for corrosion and other damage.
- Take a look at the upholstery, trim and carpets for wear.
- Make sure the seatbelts are in good condition.
- Check whether the seats are still comfortable enough.
- Make sure all lights, equipment and accessories (like air conditioning, windscreen wipers, power windows, wing mirrors, spare tyre, central locking and car radio) are there and work properly.
- If possible look for signs of rust under the carpet and don't forget to check the boot.
- Check that the jack and toolkit are in place and in good condition.
- If it's relevant, ask for the car radio's security PIN.
Start the engine
- With the bonnet open, start the engine and let it idle.
- Watch for exhaust fumes when starting the engine and during idling.
- Excessive noise from the exhaust can indicate ruse and the need for a new muffler.
- Listen for any irregular running noises, rattling or knocking in the engine.
- Look for any signs of leaks.
- Open the oil filler cap: fumes may indicate engine problems.
On the road
- Take the car for a test drive – preferably on quiet roads where you can concentrate on the car rather than on heavy traffic. Make sure the car's adequately insured before you do, and take your time – one spin around the block isn't enough.
- Make sure the engine runs smoothly when cruising, accelerating and decelerating both on flat roads and uphill.
- All gears should change smoothly up and down.
- Watch the dashboard for any warning lights and keep an eye on the temperature gauge.
- Listen for rattling or any other body noises – driving over speed humps is a good check for this.
- Watch the exhaust for smoke – accelerating uphill is a good check for this.
- The steering wheel shouldn't have more than 5cm of play.
- On a straight road, ease your grip on the steering wheel and see if the car pulls to one side, which can indicate work suspension or misaligned steering.
- Check the brakes a few times (checking for traffic behind you first). The car shouldn't pull to one side and the brake pedal should feel firm.
- What's the rear visibility like? Our report on NRMA's Reversing Visibility Index will be useful.
