I am considering buying a new G6. I am interested in the 2.4 liter model. What kind of gas mileage are you getting? Does anyone have any experience with this car? I also want a sunroof but several posts talk about leaks and rattles. Is this problem just with the panoramic roof or the regular sunroof too? I have an 8 year old Saturn and have not had any sunroof problems. Last question is the remote start a worth while feature? Thanks so much for any replies.
