The Mustang was completely redesigned in 2005. Its exterior appearance borrowed design cues from the best of the Mustang lineage, and closely resembled the design of the 1960s Mustangs. Check out that style with our 2005 Mustang Pictures. The wheelbase of the new Mustang was stretched six inches over the old model. The retro theme is continued in the interior. The numbers on the gauges are 1960's style, and the air vents are ringed with chrome. One of the most interesting features inside the Mustang is the optional MyColor customization technology. This unique feature allows the user to customize the colors of the gauge cluster; 125 different color combinations are offered.
