I was poking around for info on E400 CDI's (what an awesome car, wish they would sell it here)....turns out AMG made a C30 CDI!
Specs: 5cyl CDI, 231hp, 398 (!!) lb-ft
Funny though, with all that power its 0-60 is slower than that of the E320 CDI's being sold here (well, not in CA...and what am I talking about by "slower," either one will smoke the E300

)

Note "Kann ich fahren?" simply means "May I drive?"
