Gas prices are climbing steadily, and many drivers may soon look to trade in their current cars for more fuel-efficient models. According to AAA's Daily Fuel Gauge Report, the current national average for a gallon of regular gas is just under $3.70, which is about 10 cents higher than the average at the start of the weekend. Time Magazine reports these prices are likely to continue increasing, but when the cost of fuel rises, the price tags on smaller, economic vehicles may do the same.

Conversely, dealers tend to offer better deals on larger vehicles when this occurs. Drivers thinking about making a switch may want to figure out if the added cost of a smaller vehicle is worth what they could save at the pump. It may be more economical to hang on to their current vehicle or invest in an SUV if they need the space anyway.

"Historically, gas prices have to spike to change consumers' habits," Rebecca Lindland, an IHS automotive analyst, told The Wall Street Journal. "Even then, the change lasts only three to four months before they adapt to the higher prices. If that old SUV is paid for, running well and not costing a lot to maintain, you're going to keep it."

Drivers in the market for fuel-efficient vehicles or larger SUVs and trucks can head to New Jersey State Auto Auction, which offers a wide variety of makes and models at affordable prices. Those looking to improve the fuel economy of their current cars can drive them to Jersey City where the experts at NJ Auto's Total Car Care center can perform routine maintenance, change the oil and address any repairs. A car that runs well will consume less gas and help drivers save at the pump.
