Even though i just found this site I have practiced many of your methods since I got my first car (VW Golf)
I just bought a Toyota Yaris (4dr Auto)
And for my business I have a 1997 Ford Diesel van modified to have a 5 speed manual, currently getting 23mpg in town on Veggie oil!
(And its loaded down with Carpet cleaning equipment and water!)
I look forward to soaking in this culture of minimalism and efficientcy!
