The G6 convertible gives a nod and a wave to the fun factor. And the sunny disposition starts at the push of a button that activates the automatic unfolding of the retractable hardtop. When the process is complete, a chime is heard and the radio faceplate gives a written message that the task is done. (Putting the top in place uses the same button to complete the job in 30 seconds.) As should be expected, this is not a car for buyers who want trunk space. But there is more trunk space with top up (12.8 cubic feet) than with the top down (2.2 cubic feet). For the 2007 model year, the GT G6’s revisions include making hydraulic power steering a standard feature and adding a new rearview mirror with compass. Pontiac’s G6 GT convertible – the GTP convertible is discontinued for 2007 – can be fitted with a $1,290 sport package that includes a 3.9-liter, 240 horsepower/241 torque V6 engine, 18-inch/5-spoke alloy wheels, and stability control. The standard G6 GT convertible engine is a 224 horsepower 3.5-liter V6. When the top is down, the convertible doesn’t emit squeaks, rattles or other unwanted noises. Standard fare on the G6 GT convertible features cruise control, steering wheel radio controls, fog lamps, an 8-speaker Monsoon audio system, and more. G6 GT convertible with four-speed automatic transmission and 3.9-liter V6 engine has estimated per gallon fuel economy of 17 city/24 highway. MSRP of the Pontiac G6 GT convertible is $28,500.
