Do you know that Mercedes Benz S class  was formerly called  Sonderklasse (German for "special class", abbreviated as "S-Klasse")
No, I had no idea. That's a nice car. 
It's an A class model and was first shown to buyers in 1972 and it's been there since that time

That's nice. No, I am more particular about the S-Class because most of the latest innovation and technology is first tested on the S -Class, for example drivetrain technologies, interior features, and safety systems 
Oh, I didn't know that. So the coolest features start out first on the S class. I bet it's got awesome features these days. Does anything special stand out?
Well, The S class is rated as the world's best selling sedan and the newest model the W222 S class was first made available in 2013
Is there a convertible version?
in Mexico or sold in the United States are available in long wheelbase only.
