2013 Lincoln MKZ test drive review. Is this car worthy of Lincoln's heritage?

Lincoln is an automotive icon that has experienced some ups and downs throughout its history. During the peaks, their cars are the choice of presidents, athletes, and celebrities. During the valleys, they have been considered old ladies cars, airport shuttles, and tarted-up Fords. But right now, the folks at Lincoln are definitely climbing back up the mountain, as evidenced by the beautiful new 2013 MKZ sedan.
