It's funny how you got the opposite response than what you are expecting.
I have a 07 Altima 2.5 SL in the family, it's a really nice DD. The 2.5 got no power what-so-ever, but the CVT is smooth. I've also read a lot about how the new Altima is great. Interior looks very good! So I'd assume they improved from the previous gen. With the V6 in the Altima, it should be really good car! Not to mention that IMO the new Altima looks WAY better than the 5th Gen Legacy
