Hooray Math

I woke up this morning around 5am (usually I get up around 6:45) and couldn't fall back asleep. Why, you ask? Because for some reason I had to figure out how long a person, who spends approx. $10,000 more on a 35mpg fuel efficient car than on a regular 20mpg car/truck, would have to own that car in order to pay off the difference assuming $4.00 gas and 14,000 miles/year driving.

I haven't checked it on paper, but in my head I got about 8 years, 4 months. I was satisfied and hapily went back to sleep.

I really don't think the average American keeps their car for more than 8 years, nor do they pay straight up cash for them. There are a few approximations in the calculations, but it appears that it's better to just keep whatever gas guzzler you already have.
