| 2009 | 4dr Sedan 361-horsepower 6.0L V8 6-speed shiftable automatic RWD |
Have had the car for 1 year and 25000 km and have had no problems what so ever. I think with reasonable care this vehicle should do me for at least 10 years or more. The engine is a proven design and the car is rear wheel drive. full 2009 Pontiac G8 review |
