I agree. People can't quit magazine racing, driving around thinking "Oh my car traps 107 in the quarter mile, yours only does 103" or feeling secure in the fact that their car is .1 seconds quicker to 60 MPH (as tested by someone who probably drives much better than them).
The numbers are much better on the Mustang; skid pad, 1/4 mile, horsepower, torque, etc. but drive them both, it's a completely different experience.
The Mustang is heavy, the steering is slow and numb, there is lots of body roll due to the soft suspension. It goes like hell when you drop the hammer, and it corners well, but it's a GT car through and through.
The Z... Well, it's a better sports coupe. Tight, connected, great feedback.
I'd rather take the Mustang on a 1000 mile drive but if I'm driving just for fun it's definitely not the best choice for me. Unless you can't drive and just want to mash the gas in a straight line (or halfway through a turn exiting Cars and Coffee) or you are
actually getting paid to set record lap times, I can't see how it would be for anyone looking for a driver's car*, but maybe that's just me.
*I mean a driver's car, not a magazine racer's car.
