Something to consider. I have a 2013 Ford 5.0. When I bought the truck, gas was about $3.50 a gallon....now, in my area I can find it for around $1.40ish.
What I have started doing this year is whenever I fill up, I still mathematically figure that gas is $3.50 a gallon (3.50-1.40 = $2.10 x 25 gal = $52.50 per fill-up), and I just take the difference in what I paid and put it in a savings account for projects around the house. Eventually gas will be back up that high again, so I want to be mentally and financially prepared. So far, I'm putting about $250 a month into savings.
The point is, if it will be a financial strain with cheap gas now, do the math to see how much it will cost when gas goes back up. I saw this MANY, MANY times when I was in the car business. People will buy the big vehicles when gas is cheap. Year later, when the price goes up, they can't afford to feed it and can't trade it in because the used car value goes down proportionally.
