What passenger cars are run by diesel?
Many European makes have diesel versions. Volkswagen and Peugeot come to mind. They get outstanding milage, 1000 kilometres on a single tank of diesel is not uncommon.
BMW and Mercedes also sell diesels.
Ah here in HI, Big Island my options are lessened unless I import from the main land! Thanks for your responses. If gas was not easily available thinking diesel the best long term option.
