Over the last few months, falling gas prices have made drivers a little giddy. Just the other day, a friend who drives a compact noted cheerfully that she had filled the tank for just a little over $20, something that hadn’t happened in years. Since gas prices peaked in mid-2014, sales have increased about 8% for large pickups and SUVs while they’ve decreased about 1.5% for small cars (Edmunds.com). Lower gas prices are probably just one contributing factor to this trend, but as an easy-to-see and ongoing cost of driving a car, lower gas prices may tempt you to put that 20 mpg SUV or 18 mpg pickup at the top of your choices as you shop for a new vehicle. Before you sign for that bigger set of wheels, however, think about—and compare—several other costs of owning a car. You could save hundreds at the pump in the short term and spend thousands more long-term.
