Introducing a new station wagon in the wagon-phobic U.S. is a calculated risk for GM. Even the ultra-cool Dodge Magnum wagon from Chrysler couldn't find enough market here to hang on.
The CTS does look very slick, with a roof that tapers nicely down to that sharp Caddy back. And the new roof actually gives this CTS a little more rear headroom. Beyond that, the CTS Sport Wagon differs from the CTS sedan only in its body shape. Not that that's a bad thing. The CTS is arguably GM's best product after the Corvette.
