2. 2014 Ford Mustang Shelby GT500

A powerful coupe that easily reaches 60 mph in just 3.5 seconds. It is delivers amazing 662 horsepower and the top speed of 189 mph. And it is affordable. Althought it does not do so well in curvy roads, you can be happy with its overall performance. Acceleration is excellent, as well as braking. The interior could have been made with a little nicer materials, but you can’t say it is bad. The new model is planned for 2016.
