The Infiniti G Convertible is a G37 coupe with the added bonus of a hard top convertible. The G Convertible top stows away in less than 30 seconds! Hard top convertibles are especially desirable in Canada and the G Convertible is no exception. Driven by a 3.7L V6 and wither a 7-speed automatic or 6-speed manual transmission, the Infiniti G convertible is a RWD dream. There is no shortage of incredible upgrades and premium features.
