Hi All. I have been a long time Bonneville owner. I have (2) 2003's. One with 150,000 and other with 192,000. I am looking at buying a 2008 Pontiac Grand Prix GT. Any advice on this vehicle? Seems like it should be a really good car. Owner has it listed as a 2008 GT but I am not sure they made GT in 2008. What is the difference between a GT and non GT?. Thanks in advance for the advice.
