BMW 4 Series →
Essentially a two-door 3 Series, the 4 Series has been sold in South Africa since 2014 in coupe, convertible and Gran Coupe forms. The M4 accounts for a large share of local interest in the nameplate. Depreciation runs steeper than the 3 Series because the body styles are more niche.
Known for: 3 series style with two doors
Infiniti G Coupe →
The G37 coupe and cabriolet formed the sporty end of Infiniti's 2012 SA launch lineup, priced from R618,687; the G sedan never came here officially. A 3.7 V6 and rear-wheel drive gave it genuine pace against the German coupes. Rarity defines the used market and prices sit well below equivalent BMWs.
