Make sure there are no issues with the ABC suspension would be the biggest. That's the w215's biggest achilles heel. I'd take the one with the most documentation on maintenance for the money you are going to spend.
Supercharger pulley. I've heard these go bad. Not sure exactly what to look for here. Maybe some bearing noises in that area?
As far as reliability I don't the 06 has anything over the 04. I can't say I've ever read anything comparing them. I like the black with tan interior.
