I'm shopping for a new/ used Nissan Altima. I have been doing some searches on the body styles and new features on the 08 vs the 07 but couldn't find anything really. Can anyone point me to a site that would tell me the new features (other than the start button) on the 08 vs the 07? If it's pretty much the same, I'd rather buy an 07 for a better price. What do you think?
