The rotary-engined RX-8 sold in South Africa from 2004 to around 2011 as a relatively affordable four-seat sports coupe. Its 13B engine is fragile if neglected, and heavy fuel and oil consumption scared off many owners. Used prices are among the lowest of any sports car here, pricing in the risk of a rotary rebuild.
