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.
