BMW iX →
The iX has been BMW South Africa's electric flagship SUV since late 2021. Polarising looks and a price above two million rand limit it to a small buyer pool. Early examples have lost value dramatically, as is typical of big EVs in this market.
Known for: flagship ev with heavy depreciation
Lexus RZ →
The RZ is Lexus SA's first battery electric model, launched locally in 2025 and priced from around R1.7 million. It competes with premium electric SUVs in a market segment that remains tiny in South Africa. Like most expensive EVs here, early depreciation is expected to be steep.

Common questions
Which holds value better, the BMW iX or the Lexus RZ?
They are close to inseparable: 44% vs 44% retained after three years. Buy on price, spec and the deal you can get, not on resale.

Depreciation is the biggest ownership cost. The BMW iX loses about R 1 252 819 over three years and the Lexus RZ loses about R 937 302. 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 iX runs about R 39 309 per month and the Lexus RZ about R 29 409, before fees and insurance.
