As an alternative to the BMW 3-Series, the Infiniti Q60 (formerly G) has proven quite capable. The convertible model features 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 Q60 coupe. With a starting price of $47,000, the Q60 convertible has a healthy list of standard equipment including leather seating and HID lights.
