I've driven the Lucerne CTS for two months, and so far I'm very satisfied. It is a very comfortable, easy handling car, great on the road and very quiet in all traffic. It has great features, including the park assist, remote start and an outstanding sound system. The controls are straightforward, even those on the wheel and column. The V8 delivers the power; it drives with a robust if not sporty feel. On the downside, the backseats don't fold down, and the little pass-through port is fairly useless. The 18" chrome wheels look great but make for a pretty wide turning radius. This is my first GM vehicle, and so far it feels like a keeper.

Give folks a cargo net for the trunk, for heavens sakes; turning radius is wide, at least with the 18 inch wheels; dashboard instruments are fine at night but a bit hard to read during the day.
