The power 3.5 Lt (6 cylinder) is great I couldn't believe the way it took off when I needed to get around and ahead of congestive traffic. The back seat is roomy for several car seats, the leg room is enormous and the interior is gorgous especially at night with the sun/moon roof
I enjoy driving my G6 on the highway at night so i can see the red illuminating lights in the interior. the bucket seats are very comfortable and it has pretty good gas mileage.
I recently replaced my Jaguar XJ8. I considered and drove over a dozen cars from premium class to economy to convertibles. The car that I finally selected was the Pontiac G6 GT convertible. This car is loaded with every option available. The 3.9 liter V6 engine (yes 3.9L) provides more than enough power and torque to drive this car off the line. On the highway, it provides plenty of zip to pass and stays in the background when cruising. The engine sounds like a roadster when you accelerate. The handling is tight in the turns and crisp on the highway with no sensation of floating or drifting. Inside, the car sounds like a coupe when the top is closed, except for a little wind when you go above 80mph. Other reviews are critical of the lack of trunk with the top down. Those people should not own convertibles; what do they think should happen when you open up a hard-top? The Monsoon stereo is very impressive and my XM subscription transferred over easily. The leather seats are very comfortable and adjust to any position I need. My wife likes the adjustable pedals. Standard GM plastic makes up the dash, which is something I'll have to get used to. Overall, this car is amazing. I maintained a 3 car list while searching for my next car. Every time I found another car to go on the list, one would have to come off. The G6 went on early and never came off, so that's the one I bought. It beat out Jaguar, Ford Fusion, Mazda 6, Kia Optima, Hyundai Genesis, Mazda RX8 and a few others. If you are considering the G6 GT convertible, just go buy it. You won't regret it.
