Funny, but my 15 Civic is pretty quiet inside, easily the quietest of all the six Hondas I've owned, and significantly quieter than a Corolla or a 3. Granted, the standard for the Accord should be set higher, but if they were cheaping out on sound insulation or trying to save a fraction of MPG, you'd think they'd short change the Civic. Even my wife's 15 Fit is relatively quiet, very much so for the segment.
Also, that new Accord looks like a Saturn at first glance, much prefer the outgoing styling. And 19" wheels?! you can keep them and the expense of the tires. The 2016 civic is getting a full redesign as well and is going to look much different, with a more aggressive exterior and more conventional interior. I kind of like the current two-tier dash
