The 'good days' are over - I can't rationalize driving our F250 with its 460 engine anymore. When the policy lapses, I'll just buy day permits ($26) whenever I want to haul stuff and try to find someone to take her off my hands.... 5-12 mpg doesn't make economic/environmental sense.
On the bright side, GM has promised to sell the "Volt" by november 2010. so Ford will have to follow suit. If an electric F250 is available by 2015, I should be able to buy a decent used one by 2025 or so! Let's see, I'll be 77 years old then... still driving and willing to learn some new tricks?
