Hello,
MBs finest era has to be the 1960s to 80s and the best car to come out of that timeframe is the W116 450SEL. Of course, I mean the ROW(Rest of the World)spec W116 with the *special* rear axle suspension and simple AC-heat controls.
That is my opinion after having driven and been driven in a 450SEL, there was nothing that could touch it when it was introduced in 1972 and having owned a 1979 example for a couple of years, even at 21 years it was still a formidable machine.
The newer designs maybe more efficient etc, but all are built on engineering principles proven to WORK by the W116.
If I can ever afford it again, I would acquire a 450SEL, restore it then just drive it...........
Have a good week.
