You mention mileage being important for environmental reasons, yet you are considering a diesel powered vehicle. Are you aware that a diesel engine emits far more pollutants into the atmosphere than a comparable gasoline engine?
According to what we've read up on, urea-injection diesel systems emit H20 vapor and a small amount of NOx.
In 1950, that was true. It is not true today. Modern diesels, equipped with a particulate filter and urea injection emit less pollutants that gas engines, as well as less CO2.
