Merceds is confusing me. Are there any Merc's sold with a manual transmission? Sure, 400-500HP is impressive, even with an auto, but anything over 550HP seems...weird. And 640HP seems downright bizzare. Is this supposed to be a luxury sedan or a M5-beater (in some odd way)? How can 0-60 in less than 5 seconds be considered the better part of luxury? Desirable, sure, but gran'ma might suffer a broken rib or two should this thing start to get its game on.
Perhaps there'll be enough NBA players to sell this out for the season. :-/
