I have two good old regular vehicles with over half a million miles on them combined.
My per mile costs are a tiny fraction of what yours will be.
What, because I'll have to buy battery at some point to replace the old one? I've had this car, which has never broken down, since Feb 2001. That's 4 years. I fill it up maybe twice a month. A new battery costs a little under 3k, should I need one, and statistically I may have 5 more years. The good news for me is I want to upgrade to a Prius (mine is a 2-seater).
A little Math:
4 yrs gas for me has been about $2112 at $2 a gallon, twice a month.
These are all numbers that I can live with. I was being permissive with that $2 a gallon too :) We all know they haven't been that low in 2 years. And the way things are looking, they'll be as high as $3 or more before long.
I also have a good old regular vehicle which has served me well too. I'd like to get a nice regular Mustang one day, because they are quite cool. But for day to day stuff, I'll save my good hard cash for Wendy's and KFC.
