I spent a little while on the MB site trying to get an idea of how much additional $ MB might charge for the OM654 2.0L diesel engine, without success. Hopefully someone with their ear to the ground, or with some experience with the MB brand might have an idea if and when this engine will show up in the Metris option list, and how much extra it would be. I would really love to have a Metris now, but would consider waiting a year or two if it meant getting the OM654. I drive a diesel now (VW Sportwagen TDI). It is my first diesel, but I don't want it to be my last. I feel that a turbodiesel's torque and horsepower curves would be a perfect fit for the Metris.
