I bought my hybrid three years ago, when my family moved back to Canada and a large city (Toronto). It uses a lot less gas, is easy to park and makes me feel pretty good. Then I thought a little bit about how far it came from (Japan), the energy used to make it and transport it and all the infrastructure needed to keep it moving. That lead to the decision that instead of driving it, I should move closer to the transit system so that I could TTC to work, and walk to karate and my kids' activities. That is by far the best decision I've ever made, despite the moving costs and real estate fees on the sales of my home. Walking rules.
