Driving is pretty cheap for me. I drive an 81 VW diesel rabbit pick up that gets 45-50 MPG and I am able to do all my own service and maintenance.
I really love my little truck, consider it irreplaceable and want to keep wear and tare on it to a minimum which is one reason I bike whenever possible. Once a week I top up on diesel just to have a full tank. Last weeks top up cost me $6.25.
You should have seen the look on the face of the guy in the next stall filling up his Suburban.
