The average price of a gallon of gas is rapidly approaching $4, so it's safe to say that almost all drivers are feeling the pain. However, some may be hurting a little more than others depending on what car they're driving. According to Forbes, there are some cars which are likely to reach the three-digit mark when you're filling up at the pump.

At the top of the list is one of the most luxurious SUVs on the road today, the Cadillac Escalade. Though it's a popular ride among celebrities and athletes, it may be a bit more difficult for the average family to contend with the $120 it takes to fill up the Escalade's gas tank, according to the publication.

While the Escalade may be more of a luxury vehicle, there are some more affordable rides that still will cost a great deal to fill up. In particular, the Chevrolet Silverado, one of the most popular pickup trucks in the country, gets only 11 miles per gallon and could cost as much as $100 to fill up. General Motors seems to have noticed, and according to Forbes, is working on a more fuel-efficient version of the truck.

The Ford Expedition was once one of the most common SUVs on the road, but as gas prices rose and a push for fuel-efficiency reigned supreme, fewer consumers decided to get behind the wheel of the enormous family vehicle. Today, experts say filling up the tank could cost as much as $129.

While buying one of these cars may not be the best choice right now, New Jersey State Auto Auction offers plenty of other suitable alternatives that will save you money at the pump. With a wide variety of makes and models at affordable prices, everyone will drive away happy.
