Some people would prefer elegance and comfort, both of which the Mustang or Camaro will never have. Sure they're faster, but unless you take your car to the track or dragstrip, any car with 0-60 below 7 seconds is sufficient enough.
I've ridden in an Audi A4 Quattro with the I4 turbo. It had plenty of torque and power compared to any other grocery getter on the road.
