I traded a Focus Titanium. Couldn't stand the 7/8 sized hard seats and the dual clutch shift box. I have a 2014 V6 premium automatic and love every minute of driving it. I would have bought the 2015, but they do not make the V6 in premium trim and there is no useful back seat. I hear people knocking the V6 but let's remember it has more horsepower than 2004 and older V8s. I beat a 2004 Cobra. 0-60 in under 6 seconds with a 14.5 quarter! If you are thinking you need the V8 you need to ask yourself how big is your ego and is your wallet thick enough? And then there is range. I already fill up every 220 miles. I suspect the 5.0 needs to be filled every 150-180 miles. Ford needs to put a 20 gallon tank in these to get useful range.
Bottom line is I LIKE the luxury side of the Mustang Premium, the ride, the comfortable seats, the smooth and powerful V6, and the stunning good looks.
