buying a used car

Some people buy a used car to practise driving before upgrading to a new one, while others choose it for budget-friendly reasons. Whatever the reason may be, you want something reliable and efficient. However, with thousands of options out there, choosing the right one can feel overwhelming.

That’s why it’s important to stay cautious and informed. If you’re wondering what to look for when buying a used car, our blog has you covered. So, read our tips and buy your next vehicle with confidence.

Key Things to Check Before Buying a Used Car

Buying a second-hand vehicle is a smart financial move, but it comes with its share of potential pitfalls. Overlooking hidden issues now could lead to expensive problems later on. As such, before finalising the deal, here are some key things you should check.

  • Confirm the Owner

    Before purchasing a used vehicle, make sure the person selling it is the registered owner. This protects you from unknowingly buying a stolen car. It’s a good idea to check the registration papers and verify the seller’s ID with the name on the documents.

  • Inspect the Exterior

    First, check the doors and boot to ensure they open, close, and lock properly. Look for signs of rust, dents, or visible damage, like deep scratches. Faded or patchy paint may also suggest the car has been left exposed to the elements, which could point to negligent care.

  • Interior Maintenance

    Alongside the exteriors, the insides need a close inspection too. Make sure all seat adjustments (manual or electric) are functioning properly. Take note of any unpleasant odours, which could be caused by mould, damaged carpets or torn upholstery.

  • Look Under the Bonnet

    As part of the vehicle check before buying, inspect the engine bay for signs of neglect. Watch out for fluid leaks, excessive grime or stained components—these may suggest poor maintenance. Moreover, check for oil spots beneath the car or white smoke from the exhaust, which are signals for serious mechanical issues.

  • Examine the Tyres

    Tyres must have a minimum tread depth of 1.5mm to meet roadworthiness standards. So, anything less than this is a red flag and can lead to added expenses. Uneven tread wear on either axle also suggests issues like wheel misalignment or a bent chassis.

  • Rego and VIN Verification

    Check the vehicle’s registration (Rego) and make sure it matches the seller’s details. Then, verify the Vehicle Identification Number (VIN) on the car against what's listed in the documents. This confirms its history, legal ownership, and whether any debt is still outstanding.

  • PPSR and Written-off Checks

    To verify whether a vehicle is under finance, stolen, or written off, use the Australian Government’s Personal Property Securities Register (PPSR). This is an important step as many used car buyers only learn about outstanding finance during insurance claims.

Common Red Flags You Shouldn’t Ignore

It’s easy to get caught up in the excitement when you’re about to buy used cars, but staying alert is necessary. A clean exterior can sometimes mask deeper mechanical or structural issues. Here are some common red flags to watch for:

  • Odometer Tampering: Some sellers lower the listed kilometres on a vehicle to make it appear as if the car has travelled less. It’s a tactic to falsely inflate its value. Fortunately, there are some ways to spot this:
    • Check for signs of wear that don’t match the odometer reading, such as worn pedals, seats, or steering wheel.
    • Compare the odometer reading with the service history and rego papers.
    • Lastly, you can also request a PPSR report to see if the vehicle's recorded history aligns with the mileage.
  • Inconsistent Service Records: Gaps in a vehicle’s service history can point to missed maintenance or an attempt to conceal previous damage. Keep an eye out for inconsistencies such as different mechanics, varying workshops or mismatched handwriting styles. A missing logbook altogether is a major red flag. It often indicates poor upkeep or something the seller wants to keep hidden.
  • Mismatched Paintwork: Uneven colour or shine on panels may suggest the car has been resprayed after an accident. During your used vehicle inspection, run your hand along panel edges to feel for rough surfaces or overspray. Both of these can indicate subpar repair work. Even if the seller claims a no-crash history, inconsistent paintwork often reveals otherwise.

What to Check When Test Driving a Used Car?

A test drive is essential when buying a used car. It helps you assess the vehicle’s comfort, performance, and fuel efficiency. Be sure to test it on a mix of city roads, highways, and rural routes to understand how it handles in different conditions. During the drive, ask yourself:

  • Does it drive smoothly?
  • Do features like the air conditioning system, indicators and lights function properly?
  • Are there any unusual sounds?
  • Do the doors and windows function properly?

These checks will help you make a confident, well-informed decision. Remember, when you're buying a used car, a thorough test drive can highlight issues a parked vehicle won’t show. Above all, trust your instincts. If something doesn’t feel right, walk away - it’s worth trusting your gut.

Questions to Ask the Seller or Dealer When Buying a Used Car

If you're planning to buy a used car, asking the right questions can point you towards the right vehicle. Here are a few examples you can use before sealing the deal:

  • Why are you selling the car?
  • Can I see all the paperwork?
  • Has logbook servicing been carried out and stamped?
  • Are there any records of previous accidents?
  • What is the current odometer reading?
  • When does the registration expire?
  • Have any parts or consumables been replaced recently?
  • Is the car still under factory warranty?
  • Can I purchase an extended warranty?
  • Can I have the car inspected by my mechanic?
  • Can I take the car for a test drive?

In case you’re at a used car dealership, you should ask these two additional questions:

  • Does the purchase include free roadside assistance?
  • Can I pre-purchase a car servicing package?

Update Worth Watching: Buyer’s Market Emerging in Late 2025

The used car supply in Australia has increased by over 60% in 2024, leading to more choices and better pricing for buyers.
