2012 Ford Mustang Overview
The Boss is back. For a singular nameplate with a long history, the 2012 Ford Mustang line-up delivers a lot of choices. Any of the current Mustangs is quieter, better built, better equipped and more refined than ever, but still visually engaging and good fun to drive. Improvements for 2012 include more standard features and a selectable power steering system that changes steering effort and feedback from comfort to normal to sport at the driver's selection.
