With the CC's coupe-like appearance and dimensions come a few coupe-like compromises. There's less space inside, the rear seat is difficult to get in and out of compared to a more upright four-door, and the driving position is lower than some folks used to sedans might like.
Realistically, though, unless you frequently carry taller adults in the backseat, the CC's fashion-forward nature doesn't become a big problem. We see the CC working best for those who plan to carry a child or two in back, or who generally drive alone, with the back seat adding more flexibility than a two-door would.
There are definitely some things to be critical about with respect to the packaging, though. Headroom is a bit tight, especially in the rear, and you'll either love or hate the driving position—the seat is low to the floor and has large side bolsters that create a scoop. The three-passenger back seat is comfortable, but headroom is tight and the curvy roofline makes for a small door opening.
But there's also a lot to love--again with the caveat that you don't plan to stuff adults in the back seat. The rear seatbacks flip forward to expand cargo space when needed; there's also a well-placed pass-through at the armrest for long items like skis; and there are some useful cubbies and bins scattered around the cabin. Interior trim pieces look and feel like those in a luxury vehicle, the ride is comfortable and controlled, and the trunk is huge.
The frameless door system, a coupe staple, has another advantage: after the door is closed, the window is shut tight up against the seal, which effectively minimizes wind noise.
