As an alternative to the BMW 3-Series, the Infiniti G-Series has proven quite capable in both sedan and coupe forms. Infiniti has broadened its successful G37 line to include a convertible model. The convertible is a power-operated retractable hard top that operates in about 20 seconds. When open, the three-piece hard top is stowed out of sight under a hard cover leaving the lines of the car unspoiled. With the top closed, the hard top promises better shelter during inclimate weather. The convertible shares its 3.7L V6 engine and 7-speed automatic with the G37 coupe and sedan. With a starting price of $47,000, the G37 coupe has a healthy list of standard equipment including leather seating and HID lights. With option packages, the G37 tops $50,000 fully loaded.

The G convertible switches from a repair kit to a spare tire. The Limited Edition package is no longer available.
