Powered by an advanced diesel engine, the E320 Bluetec is as smooth and pleasant to drive as you'd expect from a Mercedes-Benz.
Unfortunately, due to ultra-strict emissions regulations in some states - among them California and New York - the E320 isn't for sale everywhere in the U.S. For now, it's available on a special two-year lease in California. That deal will be available in the other diesel-restricted states soon.
After that, a new super-clean E320 should be for sale everywhere.
