What should I check when buying a used Isuzu MU-X?

On a MU-X, check inner guards; dPD history; cold start, 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 Isuzu MU-X?

Most 2023 MU-X are advertised at $48,000 to $58,000, with 30,000 to 80,000 km on the odometer. Prices depend on the year, the kilometres, the badge and the condition.

How many used Isuzu MU-X have money owing or a write-off?

Of about 150 used Isuzu MU-X checked on Carify since November 2023, 21% had money owing and 14% were recorded as written off. Across every car checked it was 9% and 13%.

Used Isuzu MU-X Buying Checklist: What to Check

Before you go

0 of 5

What a 2023 MU-X is advertised for

Asking price: $48k to $58k
Odometer: 30k to 80k km

Asking prices, not sale prices: the middle 60% of the 683 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

0 of 17

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 MU-X

Inner guards Look above both front wheels and around the suspension towers for cracks, fresh paint or welding.
DPD history On 2017 and later cars, ask how it was driven and whether the DPD has been cleaned or replaced.
Cold start Start it cold and listen for rough idle or a top-end tick, as the valve clearances need periodic adjustment.
Gearbox Check for smooth upshifts through every gear and ask what it has towed and whether a cooler is fitted.
Oil leaks Look under the engine, gearbox and transfer case for fresh oil, and check the dipstick level.
Front end Listen for CV clicks on full lock and check for uneven front tyre wear or worn wheel bearings.
Towing wear Look for a sagging rear end, a worn towbar and an electric brake controller, which point to heavy caravan use.
IDAS On a 2021 or later car, drive in traffic and on a country road to see how the driver aids behave.

Test drive

0 of 5

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 MU-X

21% had money owing

14% were recorded as written off

Of about 150 used Isuzu MU-X 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 MU-X on the road. Money owing is what was registered against the car on the day it was checked.

Where to find the VIN

Most cars show it at the base of the windscreen, on a door pillar and under the bonnet. The registration papers carry it too.

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.
