Audi TT →
Three generations of the TT sold in South Africa between 1999 and the nameplate's retirement, with the final local range made up of TTS and TT RS derivatives. It was always more of a style statement than a hardcore sports car. Clean low-mileage cars, especially the RS, keep enthusiast interest on the used market.
Known for: design-led sports coupe
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.
