I live in the UK, and when I was looking to change my aging BMW 750iL, I considered a mercedes CL. As the kids had left home, and my wifes ML was suitable for the dogs, I thought that i would go for a 2-door. So i booked a test drive in a CL55 AMG, and was astonished at the performance. Sad thing is, I was evem more astonished by its auwful looks! I could only liken it to a CLK on steroids! Point of the matter is, that i was so impressed by the power and the drive, that i ordered a S55 AMG L and its one of the best cars I have ever owned.
Where as the CL is blatently trying to be big and flash, the S Class looks far more understated and subtle. A admire mercedes for their geniuse, but the CL is without doubt the ugliest car that they produce.
The SL on the other hand is the most gorgous car i have ever owned. It seems that the preportions are just right. Well done MB!
