Is the Mazda CX-8 a Good Used Car in Australia?

The used Mazda CX-8 is a solid choice for Australian families, offering spaciousness and comfort. However, potential buyers should be aware of DPF clogging issues in diesel models, particularly those driven mainly in city conditions.

Inspect the diesel particulate filter (DPF) for clogging, especially if the vehicle has been mainly city-driven — repairs can cost between $1,000 and $3,000.
Check the service history for regular maintenance, particularly for the engine and transmission, to ensure reliability and longevity.

Test the air conditioning system thoroughly, as the extreme heat can strain components and lead to costly repairs.
