Car enthusiasts throughout the world idolize the 1969 through 1974 Challenger. However, few are left today so, if you want a newer model that is easier to locate, the 2008 Challenger SRT8 and the 2015 Dodge Challenger SRT Hell Cat. Of course, there are many other great years, too. If you are opting for a V6, you will likely want a 2011 or later model. Before that, the Challenger with a six-cylinder engine only produced 250 hp. In 2011, the standard V6 engine was tuned to produce 305 hp. That is a big difference, and you can definitely tell when you are behind the wheel. So, you will want to take advantage of the increased power.
