I've seen G8 GT's go for low 20's, you just have to look around. We did a lot of research on the V's and decided against them after hearing about all the problems they have. The rears are noisy and break often, and they're plagued with electrical issues. The G8 is on a much higher level quality wise than the first gen V; not even a fair comparison. It's a shame you didn't post this last week, Pontiac was offering 0% financing plus rebates on 08's. They may still be, it's worth looking into.
Great post. You get a NEW car, WITH warannty and a considerable power for the money. I always liked them, Have you driven or been in one yet?.....I loved them. For about $4500 Livernois will get you over 400whp too....
