I'm saying that its not such a big deal to have a crazy bumpin system as it is to some people. The stock system in my moms camry which might sound like s*** to some people sounds good to me so as long as the G35's system is "alright" I'm happy.

The completely loaded 04 and the 06 will cost me about the same thing which is why I'm even doing this comparison thing.
I think I'm going to go for the 06 to have a car under warranty longer, the 20 extra horses and I'll probably add a navi within the next couple months.
Thanks to everyone for their help.
