I test drove the 15 GT base model a few weeks ago but before I test drove it I thought it would be great and don't get me wrong it was good. The interior was nice compared to my 12 GT and the new body style is badass. When driving the car I could feel the power and it shifted good being that it's a new car of course. I just thought the throttle response would of been better. Overall the car was good but at first I was considering trading in my 12 to get the 15 but After the test drove I'll just stick to my 12. Still a nice car though.
