Gas prices begin to fall across the Four States most places dropping below the one-dollar mark. Prices this low haven`t been seen in over two years and the low cost of gas gets people thinking about bigger cars. SUV`s are selling faster now than in recent months even with just the small drop in prices, but dealers warn buyers not to just look at the miles per gallon. When prices fall, several people come in trying to upgrade to an SUV. When they rise, the same people are back in the door wanting a smaller vehicle. Dealers say low prices make for a great time to trade in an SUV because dealers may give you more for your trade in.
