Audi Q8 →
Positioned as the sportier sibling to the Q7, the Q8 arrived in South Africa in 2019 with V6 diesel and petrol power plus the RS Q8 halo model. It carries strong status appeal in the large premium SUV segment. Expect heavy depreciation in the first three years, as with most R2 million German SUVs.

Porsche Cayenne →
Since 2003 the Cayenne has been Porsche's volume seller in South Africa alongside the Macan, offering petrol, diesel and later plug-in hybrid power. The current third generation starts around R2.15 million and the coupe body adds a style-led option. Early V8 and diesel models are now affordable used buys, but running costs catch out bargain hunters.
