Get the 06 and don't ever second guess it
The V6 has WAY more moving parts.
The V6 is new, I think has an aluminum block.
Also, doesn't the bluetec require some kind of periodic additive?
2006 = better engine, less money. See, that was easy.
EDIT: The Bluetec also comes with a 7-spd transmission. (search MBWORLD for a host of misery caused upon us by this transmision).
So to sum it up, new engine, new trans, new fuel, additive required, and a huge bill (like $4K) if you get fuel with too much sulfur in it and the particulate trap is ruined. And that's not too far fetched. Lets say a station drops 10,000 gallons ULSD on top of 500 gallons residual fuel. 10K at 15 ppm, 500 at 500 ppm, result is batch of 51 ppm sulfur......way out of spec, and YOU ARE SCREWED, damage likely not warranted.
