Based on responses to date in the Hot Rods Forum http://www.peachparts.com/shopforum/showthread.php?threadid=11842, we have two C36s, four C43s, five E55s and one CLK55 on the board, plus a 300TE with a C36 motor and an ML55, SL55 and SLK32 on order.

Looks like this confirms the relative rarity of the true AMG cars, at least here.
