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.

Toyota GR Supra →
The fifth-generation Supra returned in 2019 with BMW-sourced engines and sold here in small numbers. Production is winding down and South Africa received the run-out Final Edition at R2.82 million in 2026. The nameplate's history keeps interest high, and low volumes should protect values long term.
