I also get to claim work miles as reimbursement so any savings I can get on fuel helps me so taking a hit on electricity at home to warm the car helps as the work reimbursement is a fixed price and at home I can just put on a sweatshirt to save those pennies I used to warm the car. =)

When I bought the car I noticed that it claimed, "$600 annual fuel cost" and if the average for people is 10,000 miles a year this makes it $0.06 per mile for the car but if you drive 12,000 miles a year (average American) then this is $0.05 per mile. I don't know what number they use but I'm averaging 48.2 mpg and $0.0507 per mile. If the car's average is 49/51 mpg and I'm at 48.2 mpg but still $0.05 per mile then maybe the average driven per American is higher now. Doesn't matter. All I know is that I get more than that as reimbursement per mile so I'm happy to be "making profit" from a car for once.

--> Averaged 685 miles/week and 49.0 mpg in first year (35.7k miles from Aug 7, 2006 to Aug 7, 2007)
