you damn treehugger. its people like you that are so damn worried about the environment, it ends up costing people more money that most dont have. look at the new diesels. they all have the dpf filter, or particulate filter. makes the dodge run cleaner than the toyota prius. same with the ford. but now you wont get more than 13 mpg. while before you could get almost 20 with the 6.0l ford and 5.9 cummins. the new 6.4 ford in my buisness partners f-450 gets 8 mpg. his f-250 got 9 with the 6.4. we end up expending more natural resources to "go green" then we did before all the new emissions shit came into effect. in my opinion economy comes before environment. now this may not affect you directly, but it raises our operating costs which get passed onto the consumer. the last thing we need to worry about in a recession is the environment. just my two pennies.
