I have an 85 Mercedes sedan right now. I like the diesel engine which gets
about 27 mpg highway. I am sold on diesel, wouldn't even consider a
conventional gas -powered vehicle. I am researching larger family-sized
vehicles (used). Is there such a thing as a diesel truck (would have to be
extended cab) or a van that gets similar gas mileage, or does having ANY
large family vehicle mean poor gas mileage?
