I just bought a certified used 2007 G6. From what I can tell I made a good choice in buying this car. I'm a little confused though, I can tell that it's not the value leader trim, but it's not a GT either. I looked on a web site to c how much horsepower my car was supposed to come with. It has a 3.5 V6 but one review site said there were two 3.5's and it listed the both of them with in the 2 and 250 range. Is this true or not would really want to know this info. How can I tell?
