Where to get imported numbers
 

Most of us are familar with Nitske's production book. However, that covers what the factory made. Where can one get the numbers of each given model, that were imported into the U.S.? I am looking at a '94 E320 Coupe and per Nitske's book, in 1994 MB built only 3,234 of them for worldwide sales. I am curious to find out how many of those came here.
Thanks

No one knows where to get these numbers? I certainly can't be the only one that's interested in learning how many of their respectful models were imported.
