I do it to save money, also as a competition with my brother, to see who can spend less on gas for a given trip we make. I was winning for a while until I had to buy the Bruiser. Want to find me a 1st gen Insight once this job situation figured out, if i can. Another big part of it is that every dollar i don't burn through the tailpipe is another dollar I can spend on restoring the Edsel.
