Now 36 years old, the Mustang is quickly approaching middle age. Fortunately, it received a facelift and a serious dose of testosterone in 1999. The facelift sharpened the Mustang's looks considerably (some people like it, some people don't). Changes in styling were applied to the doors, hood, decklid, quarter panels, taillights and headlights, rocker panel moldings, side scoops and C-pillar appliques. And even more importantly, both the V6 and V8 engines were modified to produce additional horsepower. Learn more about the 2000 Ford Mustang GT.
