East Coast West Coast Benz Battle: CLS550 4Matic versus CLS550



So you need a Mercedes-Benz with a giant V8, about 5.0-seconds to 60-mph or less, and perhaps four doors -- perhaps only two.

Options will lead you to the CLS, the original "foupe" and inspiring act for the very fashionable new CLA250 and CLA45 AMG.

?????????????????????????? ?????????????????????????? ?????????????????????????? ?????????????????????????? ?????????????????????????? ????????????? ?????????????

This is not really a Tupac vs Biggie-style rap battle.

Just noting that the CLS550 is available both in rear-drive and AWD setups.

They are both very tail-happy and will play along when you are in the mood.

But once the CLS trigger is pulled, you might be compelled to only consider the CLS63 AMG. While that is an exceptional vehicle, and the epitome of a big dom V8, the CLS550 is still the 'full business.'

And a cool $10,000 savings will never hurt the wallet either. Only a s light dent in pace is barely noticeable, but the far comfier ride quality will be appreciated by all occupants.
