I've done some better analysis on numbers of E500, using the data from howmanyleft.co.uk. I had to guess at when each new model came out though, so I might be a bit off.
600 of the W210 / S210 5.0 litre (2000 to 2003)
85 of the W211 / S211 5.0 litre (2004 to 2007?)
63 of the W211 / S211 5.5 litre (2008 to Q1 2009?)
154 of the W2112/S212/C207 5.5 litre (Q2 2009 to Q1 2011)
43 of the C207 4.7 litre TT (Q2 2011 to Q1 2013)
howmanyleft lists the number of each model sold per year, and after 2009 it lists by calendar quarter, making it easier to guess when each new model came out.
It doesn't show which body type out of the W, S and C, because Merc did not include that in the model name descriptor that it provided to the DVLA.
All in all, any E class V8 after 2004 was a very rare car! There are many more E55s (over 1000) and E63s (almost 2000).
