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 
My dad actually drove one in the 1980's.  It was the 300S.  Super nice car. What about the C class, do you know anything about those?
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?
i'm not so sure but since, they started it in 1972, there have been 6 generations of it
Cool. Anything else interesting about it?
