Buying a BMW X5 in South Australia
G05 X5 (2018+) M50i has documented N63B44 V8 timing-chain guide wear at 100,000km — a $14k repair. Verify dealer service stamps; non-BMW oil voids the warranty silently. The xDrive transfer-case actuator on E70/F15 examples (used market) is a known $3k failure.
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.
