What has been a rumor for a long time is reality now: Mercedes AMG offers a G 55 Kompressor model with the same engine specs/power as the E55 AMG. 0-62 mph acceleration time is the same as on the Porsche Cayenne Turbo, top speed is limited to 210 kph due to safety reasons.
Cost in Germany is around 108000 Euro incl. VAT.

Mercedes also offers a ML "Final Edition" model for the german market, for other markets maybe too. It seems that the "end" of the ML is coming...
