The W210 E-Class came out in 1996.

The Chrysler LX platform is an, um, "adaptation" of the Mercedes W210 platform.

If you think about it though, plenty of vehicle platforms last long times with refreshes and updates at some point or another. The same basic architecture that started out in the 1988 Civic made its way all the way up to the 2001 Integra, for example. The current Honda global midsize platform (Accord, TSX, TL, etc) still has a lot in common with the 1990 Accord. Plenty of other companies do this too.
