Rising gas prices may be causing some people to worry, but it could actually be good news for anybody looking to buy a used truck. As fuel-efficient cars become more in demand, the prices of pre-owned pickup trucks are likely to drop significantly, according to Automotive News.

Some estimates put the figure at about a 22 percent decline in price and it is directly tied to the instability in gas prices. Experts say that as tensions in the Middle East continue to grow, there could be a chance of gas prices reaching the $5 per gallon mark. According to the National Automotive Dealers Association (NADA), $4.50 a gallon would result in about a 9 percent drop in used pickup prices.

"We are always making vehicle price adjustments based, in part, on our expectations for the price of gasoline," NADA analyst Larry Dixon told the news source.

While that may be bad news for dealers, it is certainly cause for celebration among consumers, especially those who have been driving pickup trucks for years. But what are the best used pickup trucks to get? According to Vehix.com, there are many good options to choose from.

Among the best is the 2006 Ford F-150. There's a reason this truck is always one of the best selling cars in the country. According to the website, the 2006 model was especially reliable, not to mention it can tow up to 9,000 pounds.

Whether you're looking for a used Ford F-150 or a Chevy Silverado, New Jersey State Auto Auction has plenty of pickup trucks to choose from. With a wide variety of makes and models at affordable prices, there is something for everyone.
