There are several 400E models available in my area for $20,000-$22,000. Are they worth the difference from the $15,000-$17,000 300E models? I read the profiles on your site. They seem to have more power, etc. Do they have more mechanical problems? Also there are c280 models available for roughly the same price as the 400E's...no good?
Also, any recommendations on a shop in Miami where I can bring in the car for an inspection...prior to purchasing it.
