OK, that title is a stretch...there might be a prize for the person who figures out the reference.
I just saw this on another blog I read and I love it!
It is a little calculator to decide if you should buy a more fuel efficient car or stick with the one you have. It's based entirely on economics, but still interesting. It IS more environmental in general to keep using things you have, including cars and houses, than to buy something newly made so the economics are probably enough.
So, here it is:
SHOULD YOU BUY A MORE FUEL EFFICIENT CAR
Just fill in the info and see what you get.
I found out that given my 30mpg I get in the subaru, and the price of gas, even driving 3000 miles a month (yes, 3000 is my current monthly milage...cripes) it would take me 14 years to recoup the cost of a better car and that was only paying 7500$ for that car. I have not met the 7500$ car that runs for 14 years (though I keep trying).
And, I will not be driving 3000 miles a month for 14 years so the recoup would actually never happen.
Nice to have it confirmed that driving my car into the ground is not only simple, frugal and environmental (as long as I maintain it), but also cost effective.
