Compared to what? It isn't a "drag" car. It's a FWD, 1.8l N/A 4banger. Weighs 2500lbs. The car handles like a dream for a car that costs about 22k.
You can say that the 15+ second mr2 spyder and mazda miata aren't impressive by 1/4 mile numbers too, but i'd take either one of those over a mustang in a heartbeat. There's more to driving than 1/4 mile numbers.
