G6s are garbage, they replaced the Grand Am which should tell you plenty about their build quality. If I were you I would look into something like a Mazda 3 or 6(I am biased to Mazdas lol), Honda Civic, perhaps something like a Corolla S.
what do you want it to do? for 9 grand u can buy something around an 00' and upgrade tires, intakes, good sound system.. etc
