As a two car family i believe I have the best of both worlds. I love to 4-whell on the back roads of Arizona and therefore have purchased the H2 for that purpase. I don't just mean casual four whelling but like the challenge of putting the H2 to the test. I know its a lot of money to spend on a vehicle that ends up with lots of Desert Pin Stripes and a few heavy scratches which only a new paint job will fix.
The second vehicle is a VW Jetta Deisel which gets 45mpg when I last checked. There is no need to purchase Petro Deisel if your looking to help the OZone. There is currently a product out called Bio-Deisel which comes from soybeans. You can buy it in blends B-20, B30, ect. B-20 means 80% Petro Deisel usually #2 Deisel and 20% soybean. Did I forget to say you can also buy it 100% soybean and the VW runs great with that blend.
The fuel is sold in Phoenix at a few stations which I can only hope for more to carry in the future. The price is a little high, $2.50 per gal, but when you get 45mpg its not to really that much. It equates to 22mpg instead. It is an excellant product which we use on all our fleet Deisel vehicles.
So if your interested in helping the environment buy a second car that burns Deisel and start using Bio-Deisel as an alternative fuel. Alternative fuels qualify for HOV lanes, which the state will have no alternative but to let those who use Bio-Deisel use the lane as well.
