I test drove a CT6 a while back when it had that Northstar engine. For my tastes, way too big and way too floaty. I think they did have a "V" version at some point, I didn't drive it. I was semi-interested in a CT4 BW at one point. Reality is for us olsters, the Tucson works pretty well, decent room, quiet ride, OK acceleration, OK mpgs. We drove out to Monroe, GA today and I was musing that it's a pretty OK vehicle, for us. Just boring.
I might have gone for the BMW X1 except for its transmission.
