( http://www.TFLcar.com ) The new second generation of the 2013 Mercedes-Benz GL will be at your local dealership in the fall of this year. For 2013 Mercedes-Benz has completely revamped the model line including the V8 Mercedes-Benz GL 450, 550 and the diesel BlueTec 350. We recently had a chance to drive all three version of the GL in New Mexico both on and off-road and came away impressed by the list of luxury and safety items that are now both standard and available on the biggest 7 passenger  luxury SUV in the Mercedes Benz lineup of new cars. Check out this first drive reviews we pul all three to the test.
