Here is my suggestion.

Using a pickup as an everyday car is about done for most of us. Buy a little junker car that gets 30+ miles to the galllon.

I spend about 35.00 bucks a week for gas, and I car pool. They money I save goes into a "Gas" fund for trips. Set a budget for Gas for everyday use. Trim that amount in order to start this gas fund.

I budget 70.00 dollars a week for Gas, I am currently using around 35.00 dollars the rest goes in my Gas fund, yeah I have a Gas fund[&:]
