Edmunds has taken the time and reviewed the new CL550, and has nothing but positive things to say about the gorgeous CL. While it was hard for Mercedes to out do themselves with the new model, they actually did it, and the CL and the many positive reviews are the proof. Here is a great quote that sums the review up.
Most of our time in the CL was spent on roads that rarely complemented its size or intent, yet we still had a hard time finding anything wrong with the big coupe. It looks better, goes faster and feels more comfortable than its nearly perfect predecessor. There’s too much weight on board to throw around quickly, but if you want light buy a Lotus. If you want a luxurious, quiet and fast GT, the CL550 is as good as any car on the road. And thanks to Mr. Hutzenlaub, it looks good doing it.
