The sickle-shaped control arm is a wonderful thing: It provides an easy and relatively cheap way to locate and control the bottom of a MacPherson strut. Which car is this one mounted to? (Hint: It's not a Lotus.)
Answer: The 2010 Ford Mustang. Why is this one on its side? Because Ford wants you to see the business end of the horse. (No jokes, people. This is a serious matter.)
