I just checked REV, the margin is slimmer than originally thought.
MotorTrend states at

Porsche Boxter S: "In the end, our best run to 60 mph was 5.8 seconds, while our quickest run through the quarter mile took a scant 14.2 at 98.8."

99 Mustang GT: "0-60 mph in 5.4 seconds and a 14.0-second/100.2-mph quarter-mile run is as good or better than any stock Mustang we've ever tested, Cobra or not."
... and there is still the street drive performance issue you know.
