What should I check when buying a used Mazda 3?

On a Mazda 3, check dashboard; steering; diesel oil history, on top of the checks for any used car: the body, tyres and engine, a test drive, and the paperwork for money owing, a write-off and the odometer.

How much is a used Mazda 3?

Most 2014 Mazda 3 are advertised at $10,500 to $16,000, with 95,000 to 185,000 km on the odometer. Prices depend on the year, the kilometres, the badge and the condition.

How many used Mazda 3 have money owing or a write-off?

Of about 2,600 used Mazda 3 checked on Carify since November 2023, 4% had money owing and 25% were recorded as written off. Across every car checked it was 9% and 13%.

Used Mazda 3 Buying Checklist: What to Check

Before you go

0 of 5

What a 2014 Mazda 3 is advertised for

Asking price: $10.5k to $16k
Odometer: 95k to 185k km

Asking prices, not sale prices: the middle 60% of the 1,085 advertised in the last 12 months, one listing per car.

Get the rego or VIN From the ad or the seller. Enter it at the top of this page: the make, model and year should match the ad.
Compare the price With what similar cars are advertised for.
Ask the seller How long they have owned it, why they are selling, any accidents and any money owing.
Ask for the service book And for the engine to be cold when you arrive.
Meet in daylight In dry weather. For a private sale, at the seller's home: the address should match the registration papers.

Inspection

Panels and paint Uneven gaps, paint that does not quite match and overspray on rubber seals point to accident repairs.
Rust Under the doors, around the wheel arches and under the boot floor.
Tyres At least 1.5 mm of tread, even wear across each tyre, and a spare.
Glass and lights No chips or cracks in the windscreen, and every light works.
Oil and coolant Check them cold. Milky oil under the filler cap, or oil in the coolant, can mean a head gasket fault.
Cold start Watch the exhaust and listen for rattles in the first few seconds.
Wear inside The pedals, steering wheel and driver's seat should fit the odometer reading.
Warning lights and controls Lights come on with the ignition and go out once the engine runs. Try the air conditioning, windows, locks and screen.
Flood signs A damp smell, water marks or silt under the carpets.

What to check on a Mazda 3

Dashboard On BK cars look for a crack across the dash top. On 2009 to 2011 BL cars, touch the dash for a sticky, shiny surface.
Steering On a 2007 to 2009 BK, check the steering is light at parking speed and the power steering warning light stays off.
Diesel oil history On a BL Diesel, ask for receipts showing regular oil changes and whether the oil pick-up strainer has been checked. Walk away from one with a history of oil warnings.
Gearbox On 2011 to 2014 autos, listen for a whine that rises with road speed and watch for revs flaring between shifts. On manuals, make sure third gear holds over bumps.
Fault codes Have the car scanned. Codes such as P0015, P0524 or P0191 on an early SkyActiv-G can point to the oil pump or fuel pump faults.
Infotainment Use the screen and dial for several minutes, pair a phone and watch for freezes, reboots or phantom inputs.
Battery and stop-start On a BP, ask whether the car has had low battery warnings or software updates, and check i-stop restarts promptly once warm.
Service and recall records Check the logbook for on-time oil changes and ask for proof of recall work, especially the 2.5 software update on 2019 BP cars.

Test drive

20 minutes or more On slow streets and at highway speed.
Steering and brakes It runs straight with your hands light on the wheel, and stops straight without shudder or squeal.
Gear changes Smooth, with no slipping or flaring revs. In a manual, a clutch that bites near the top of the pedal may be worn.
Noises Knocks over bumps, and whines or hums that rise with speed.
Temperature and leaks The gauge settles and stays put. After the drive, look under the car for fresh drips.

Paperwork

0 of 7

Money owing A car with finance owing on it can be repossessed after you have paid for it. A PPSR check shows it.
Write-off A statutory write-off can never be registered again, and a repairable write-off needs an inspection first.
Odometer Compare the reading with earlier records of the car: service book stamps, earlier listings and other records.
VIN match The VIN on the car matches the registration papers and the PPSR certificate.
Seller's licence The name and address match the registration papers.
Safety certificate In Queensland the seller needs a current safety certificate, and in Victoria a roadworthy certificate is needed to transfer the registration.
Receipt The date, the price, the VIN and rego, and both names and signatures.

Money owing and write-offs on the Mazda 3

4% had money owing

25% were recorded as written off

Of about 2,600 used Mazda 3 checked on Carify since November 2023. Every car checked: 9% had money owing and 13% were written off.

These are cars people chose to check before buying, so they are not a share of every Mazda 3 on the road. Money owing is what was registered against the car on the day it was checked.

Where to find the VIN on a Mazda

Older cars also carry a compliance plate, usually under the bonnet or on a door pillar. A car supplied new since mid 2021 may have none: it is entered on the Register of Approved Vehicles instead.
