Exterior

The ATS looks good on the road. You never can tell for sure at an auto show, where I thought the headlights were too slit-like, and I wasn't sure about the hump in the trunk lid, accented as it is by the combination spoiler/brake light. I'm still not sure about the latter, but it's not bad with certain exterior colors. If anything, Cadillac could have taken the design further; it looks conservative compared with the CTS' giant grille and flared fenders.
