when is cutoff date for E320 MB engine?

I was wondering when did they make last E320 with original Dimler/Benz engine.
I see some 97 have I6, but I am not sure if it's Chrisler 6 or MB.
Thanks,

they never used a daimailer engine in the MB, They where two company's with congioned ideas, they used the MB engines in the dodges or the chryslers i should say like the crossfire
