2011 Ford Mustang V6 Premium 2dr Coupe (3.7L 6cyl 6M)
I had a 2005 and this is a whole different car. Performance and handling are excellent and gas mileage, considering performance, is excellent too. With 4000 miles on it now I average 20.5 locally and 30 highway (manual transmission). I also have the MCA package, heated seats, and rear view camera (surprisingly convenient). One thing I would change would be to get the 3.31 axle. With the standard gearing it isn't turning high enough rpm to easily maintain speed on hills in 6th gear and legal highway speeds. 6th is pretty useless below 70 mph.
Styling and performance
Move the cup holders and change the latch on the console lid (tends to open with your elbow). Make 3.31 axle the standard.
