I live in a very rural area and there is no way I could manage without a car because I need it to get me to work. I can't just move to another city where I could theoretically get by without a car, because then the other things that I do save on here (namely: rent, entertainment, etc) would go up there. My boyfriend and I are fortunate enough to work at the same place so we only have one car, which we bought used for cash. We are able to walk or bike to local grocerey stores, the library and parks, so we really only use the car for work and when we go on trips (ie: to walmart haha).
We have a giant apartment for less than $600 a month (incl. everything but electricity, for which we average about $25). This same apartment would cost us at least $1000 in a larger city with public transit. Now we could move into a studio and pay $800, but not really worth it mentally. Been there, done that.
Plus we have an abundance of free entertainment outside our door. Biking and hiking trails in the summer, ice skating, snow shoeing and skiing in the winter. The small town life is a lot slower-paced and does actually help with the finances, at least for me, because there are less things luring you as you walk down the street. I lived for two years in metropolitan areas and spent a good $150 a month on clothes and eating out just because of all the opportunities I had. Plus when I had no car I had this very oppressive feeling on dependence upon others and I was spending $50 a month at least on public transit.
I think most of these lists are geared toward metro-people, I should make a list for rural folks. ie:
Chop your own wood instead of having it delivered already chopped (for the wood furnace)
Ask your neighbors if they want to come along and share gas money when you go to Walmart or Costco.
