A plunge in the price of gasoline over the past six months has drastically changed the result of the calculation new car buyers and drivers perform every week: How much is it going to cost me to fill this thing up?
The national average price of gasoline Monday was $2.13 a gallon, according to AAA, after falling for a record 109 days in a row. Six months ago it was $3.63 a gallon.
That Chevy Tahoe you were eyeing will cost $39 less to fill up than it did in July. The Honda Fit now costs you just $23 to fill the tank. Maybe you can afford to throw in the booming premium stereo.
For hybrid cars or plug-in electric vehicles, though, cheaper gas means it will take much longer for fuel savings to make up for the extra up-front cost of a car with a big battery.
