what is the core competence of AMG, what is their philosophy? building sport cars? IMHO not. even though they canned the A21 AMG, these guys have no scruples doing ANYTHING. at least the price tag is high and the engine is kind of powerful. while audi's "quattro GmbH" and BMW's "M GmbH" are modifing a lot more of the car, AMG is basically implementing an egine and adding some aftermarket style bodyworks -- compare the C32 AMG with the M3 or the RS4...

to me, AMG is kind of a "premium merc", but not a "sporty merc". so i have no problem with an AMG diesel.
