Pre-purchase car inspection in Perth

In WA, nobody checks a used car for you. Here's how to do it properly.

A pre-purchase inspection matters more in Perth than in most places, because a WA private seller doesn't have to get any roadworthiness check before you hand over the money. Consumer Protection WA strongly recommends paying for an inspection by a qualified mechanic before you buy a used car. Put the seller's postcode in the card with the make and model, and a Perth mechanic who inspects that kind of car gets the job.

Why Perth buyers need their own inspection

No roadworthy on a WA sale

The transport department's steps for selling a WA-licensed car are a notice of sale within 7 days and handing the buyer the licence paper. There's no inspection in that list, so the car can change hands without anyone looking it over.

Private sale, your risk

Consumer Protection WA says that when you buy from a private seller, you're purchasing at your own risk. Cars sold privately aren't covered by the statutory warranties under the Motor Vehicle Dealers Act, and nor are cars at an auction run for a private seller.

Dealer warranties run out fast

From a licensed dealer, a car no more than 10 years old with no more than 150,000 km gets a statutory warranty of 3 months or 5,000 km, whichever comes first. Between 10 and 12 years, and 150,000 to 180,000 km, it's 1 month or 1,500 km. Beyond that there's none, and commercial vehicles built mainly to carry goods are excluded, though the consumer guarantees still apply.

Cars from over east

Every interstate vehicle has to be inspected at an Authorised Inspection Station and given a certificate before it can be licensed in WA. If you're buying one to bring here, budget the time for that as well as the mechanic's check.

Isn't the DoT inspection the same thing?

No, and it's an easy mix-up when you search for a car inspection in Perth. The transport department says its inspection only decides whether a vehicle meets the standards for licensing. It isn't a full assessment of the car's condition and shouldn't be used to value one. Vehicle inspections in WA covers that side.

A pre-purchase inspection is a mechanic telling you what's wrong with the car, what's about to be, and what it'll need soon, before you've agreed a price.

What a good Perth pre-purchase inspection looks at

  • A road test, including a cold start if the seller will allow it.
  • Engine, cooling system and transmission, and any leaks underneath.
  • Brakes, tyres, steering and suspension.
  • The battery and charging system.
  • Heat wear: hard or soft hoses, cracked belts, coolant stains, and air conditioning that blows warm.
  • On a 4WD or ute: the driveline, diffs and underbody for signs of hard off-road or beach use.
  • On an electric car: the high-voltage system, including a look at the battery.

What you can check before the mechanic goes out

  • Run a PPSR search on the VIN to see whether the car is a repairable write-off, stolen or still has money owing.
  • Read the service history in the logbook and match it to the invoices.
  • Compare the odometer with the car's age: a typical Australian driver covers roughly 12,000 to 15,000 km a year.
  • Ask whether any maker's warranty is still running from the original sale.
  • If it's an interstate car, check for an open Takata airbag recall, because WA won't inspect a car with defective Takata airbags until that's fixed.

Our take

We'd arrange the inspection before talking price, and we'd walk away from any seller who won't allow one. In WA nobody else is obliged to check the car for you, so a mechanic's report is the only independent opinion you'll get. Send the job with the seller's postcode, since that's where the car is.

Questions people ask

Does a WA private seller have to give me a roadworthy certificate?

No. WA has no roadworthy requirement on a private sale, which is why an independent inspection is worth paying for.

Can the mechanic inspect the car at the seller's place?

Many inspections are done where the car is parked. Put the seller's postcode in the card and mention in the note if it's at a dealer's yard or a home.

What happens if the inspection finds problems?

You can use the report to negotiate, ask the seller to fix things before the sale, or walk away. Ask the mechanic to separate safety items from things that can wait.
