Gas really isn't a big worry for us. I am stay at home and my husband works .3 miles from work. He could easily walk. The kids school is .2 miles from home and most of my family lives within a 5 mile radius. A lot of them in less than 1 mile.
We also have an older Oldsmoble car that has about 80,000 miles on it and is good on gas. It runs pretty good, and we would use it mostly now. currently with us driving the corolla so much it can go more than a week without anyone driving it.
My biggest concern is how long would it be before we have to replace them.
