Right now I am driving a 06 Grand Prix GXP and I like the car but I am bored with it and it has a ton of rattles that drive me insane. I stoped by my dealer and they said they have a G8 coming in on trade Saturday and I should come in to look at the car Saturday. If the numbers work out should I make the switch? I know a couple people have G8s around here, how is the quality of the car? Does it make any interior squeakes and rattles? If I get the car I want to keep it for a long long time.
