I love my GM, but the new mustang's are very nice.  They are a very nice car overall if you want something that drives nice, goes fast in a straight line, or can dice up the twisty tracks.   
After Brady took me for a few passes down the track I was sold, after he pulled a 12.06 with few mods I was really sold.   
Downside, it would suck to drive in the snow.
