When will you guys ever come to your senses? It WON'T happen. Someone does not want the US driving population to get used to the idea that diesel is 30% more efficient, and costs less to manufacture than Regular Unleaded.
1) BigOil wants you to keep using your GMC Subdivision
2) Bringing in the COMPLETE line of Mazda, Honda, Toyota, VW, AUDI, MB diesels to the US will absolutely destroy Ford, Chrysler, and GM. Forget about the Japanese cars. Let's just talk about VW. Look at the European line. Almost all have a diesel motor option. Bring them in, and people start seeing 50-60 MPG, better handling cars, better styling, and the LeBarons, Skylarks, Fusion Titanium (just the name, not the connecting rods), Taurus, Impalas, Chargers will look like a bunch of cardboard boxes.
