BMW Z4 →
The Z4 replaced the Z3 in 2003 and has run through three generations in South Africa. The current car shares its platform with the Toyota GR Supra, and production ends in 2026 with local stock on runout. Roadsters are a small niche here, so both used supply and demand are thin.

A two-seat electric roadster with 375 kW, scissor doors and a 3.2-second 0-100 time, sold here from MG's relaunch at R1,399,900. It exists mainly as a halo car and volumes are tiny. Expect steep depreciation typical of high-priced EVs from newer brands.
