The rear seats are quite a rarity, but if you are content with a four seater, there are lots of CL55 AMG or a CL600 out there which some say (me included) much classier cars
Id have to agree that the CL600's and the CL55's are very nice cars and while i understand that the CL's are actually just coupe versions of the S-Class one of the big objectives of getting my next car is the amount of space in the back. Each to their own i guess but while the CL may look better the S55 seems to suit my needs more at this time, hence why im getting an "L" version. He who cant sit in the middle seat has enough room to lie down on the floor
Plus the CL's LOOK like sports cars and go like sports cars, while the S class is more of a sleeper and you wouldnt expect it to do the kind of damage that it can.
