great article:

this article explains why a hybrid vehicle is great for around town driving but a regular diesel is better (more economical) for long highway driving, retains its value and lasts longer than a gas vehicle.
so the ultimate combination for the future,,,for a two car family will be to own one diesel vehicle and one hybrid... and that is now my plan.
