Personally, I think the only new vehicle this 2008 year that is going to rival cadillac is the XF. Others fail to come close in the mid Luxury price range. This is indeed a Shocker to imports, Just as the $$ is falling1. Cadillac CTS: This car has the best steering feel of the group. The G35's is quicker (faster ratio) but it's also heavier and, honestly, a bit too hyperactive. The Mercedes' is similar in feel and ratio, but it doesn't deliver the intuitive feedback that the CTS offers. Ride quality is softer than either, and it feels like the biggest and heaviest of the group -- probably because it is. It also has the best interior design in my opinion, though there are subtle aspects of its interior quality that could be better. In terms of audio/entertainment system -- both design, ergonomics and quality -- it nukes the others.
