It’s more like, “What’s not new?” The 2007 Chevrolet Suburban rides on a new, fully boxed frame that boasts a new coil-over-damper front suspension and new rack-and-pinion steering. The interior has been completely reworked with higher quality materials and more cargo space (137 cubic feet compared to 132 for the previous model), the exterior has been redone, it offers more power, it runs quieter, has more safety features, and it is more fuel-efficient.
