Mazda 6 Check — South Australia

Buying a Mazda 6 in South Australia

Mazda 6 (GJ 2012-2023) is discontinued in AU — last shipments in 2023. 2.5T (Atenza) shares engine with CX-9 — same intake-valve carbon issue at 100,000-130,000km. Skyactiv-G NA has the cylinder-deactivation rumble (normal but jarring).

Specific to South Australia: South Australia's used-car market is smaller than the eastern states but proportionally similar in composition. Adelaide's lower theft rates make it one of the cheaper states to insure a high-value vehicle — but interstate vehicle transfers (particularly from QLD and NSW after major weather events) make NEVDIS WOVR checks essential.

Common issues on used Mazda 6

These model-specific concerns affect any 6, regardless of state of registration. Use as a checklist when inspecting privately.

1. Intake-valve carbon buildup at 100,000+ km (DI 2.5T)
2. Cylinder deactivation rumble at 1,500-2,000 RPM (NA)
3. Front-bumper paint chip from highway use
4. Wagon variant rear-shock wear

South Australia written-off vehicle rules

SA's WOVR is administered by Service SA and feeds NEVDIS. Same statutory/repairable distinction as other states. SA additionally operates a 'Notified vehicle' register for vehicles with structural concerns short of full write-off — verify this notation is absent on NEVDIS.

South Australia-specific things to verify

• Service SA conducts random VIN inspections during transfer
• SA stamp duty is calculated on the higher of dutiable value or market value
• Roadworthy not required for private sale (caveat emptor)
• Adelaide Hills examples often have higher rust on undercarriage from cooler/wetter climate
