BMW X5 →
One of the first premium SUVs in South Africa, the X5 has been on sale since 2000 and remains a status benchmark. The xDrive30d diesel has been the perennial volume derivative. It is a used-market staple, though out-of-plan running costs on older examples are high.

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.

Common questions
Which holds value better, the BMW X5 or the Porsche Cayenne?
They are close to inseparable: 60% vs 59% retained after three years. Buy on price, spec and the deal you can get, not on resale.
Which is cheaper to own over three years?
Depreciation is the biggest ownership cost. The BMW X5 loses about R 723 120 over three years and the Porsche Cayenne loses about R 878 516. Fuel, insurance and servicing can narrow or widen that, but the depreciation gap is the number to start from.
What do they cost per month?
On typical finance (10% deposit, 72 months, 11.75%), the BMW X5 runs about R 31 717 per month and the Porsche Cayenne about R 37 561, before fees and insurance.
