I was looking at getting an '07 Civic, and while I still feel it's a beautiful car I also feel like it's missing a lot of the bells and whistles that I've grown accustomed to. Would moving up to an Acura CSX be worth the extra money?

get the one you like
no one here on this Board has both cars and can tell you which one you will like more

If you're looking for bells and whistles then get the acura, if you're looking for reliability then get the honda. I worked in the service deparment at an acura dealership and those bells and whistles break down a lot.
