2009 Mercedes Benz CLS550

I know the CLS is basically a better looking E-class, but every time I look at a CLS I think it should be as large as an S-class inside. Then I try to put adults in the back seat and it's a bit too small for taller folks. The swooping lines of the coupe make the vehicle look longer than it actually is. I didn't think about the XF at all when I was behind the wheel of the CLS, but I did miss the thrust of the CLS63 AMG that just graced our test fleet. The tip-in on this CLS550 isn't terribly aggressive. It's sort of a Mercedes trend, but this car felt just a little heavy and sluggish. That doesn't mean the car is slow, but the tactile sensations lead you to believe the CLS is more dignified than in a rush, even under full throttle. Buyers may not even care about this since the main reason to buy a CLS is for its looks and luxurious interior. Phil Floraday, Senior Online Editor
