I know for a fact that the W126 S-Class was the best selling large Mercedes since ever. Over 800K W126 were produced in 13 years. The W220 did better than 600K, but this was only after a span of 8 years (1998 was the first year in Europe).
"Production of the 190 ended in Sindelfingen in February 1993 and in Bremen in August that same year. A total of 1,879,629 vehicles had been manufactured"
