Buying a Audi A5 in South Australia
B9 A5 (2017+) shares EA888 + S-Tronic with A4. RS5 variants use the 2.9L bi-turbo V6 also found in Porsche Panamera — carbon-buildup at >100,000km is documented. Sportback variants have rear-hatch power-strut wear at 4-year mark.
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.
